New for the subsequent release: * The Andrew Watson, Vice President and Technical Director of the Object Management Group, has officially assigned us 20 bit Vendor Minor Code Id: 0x47430 ("GC") that will mark remote Classpath - specific system exceptions. Obtaining the VMCID means that GNU Classpath now is a recogniseable type of node in a highly interoperable CORBA world. * Classpath now includes the first working draft to support the RMI over IIOP protocol. The current implementation is capable for remote invocations, transferring various Serializables and Externalizables via RMI-IIOP protocol. It can flatten graphs and, at least for the simple cases, is interoperable with Sun's jdk 1.5. New in release 0.18 (Sep 6, 2005) * GNU JAWT implementation, the AWT Native Interface, which allows direct access to native screen resources from within a Canvas's paint method. GNU Classpath Examples comes with a Demo, see examples/README. * awt.datatransfer updated to 1.5 with supports for FlavorEvents. The gtk+ awt peers now allow copy/paste of text, images, uris/files and serialized objects with other applications and tracking clipboard change events with gtk+ 2.6 (for gtk+ 2.4 only text and serialized objects are supported). A GNU Classpath Examples datatransfer Demo was added to show the new functionality. * org.omg.PortableInterceptor and related functionality in other packages is now implemented: - The sever and client interceptors work as required since 1.4. - The IOR interceptor works as needed for 1.5. * The org.omg.DynamicAny package is completed and passes the prepared tests. * The Portable Object Adapter should now support the output of the recent IDL to java compilers. These compilers now generate servants and not CORBA objects as before, making the output depended on the existing POA implementation. Completing POA means that such code can already be tried to run on Classpath. Our POA is tested for the following usager scenarios: - POA converts servant to the CORBA object. - Servant provides to the CORBA object. - POA activates new CORBA object with the given Object Id (byte array) that is later accessible for the servant. - During the first call, the ServantActivator provides servant for this and all subsequent calls on the current object. - During each call, the ServantLocator provides servant for this call only. - ServantLocator or ServantActivator forwards call to another server. - POA has a single servant, responsible for all objects. - POA has a default servant, but some objects are explicitly connected to they specific servants. The POA is verified using tests from the former cost.omg.org. * The javax.swing.plaf.multi.* package is now implemented. * Editing and several key actions for JTree and JTable were implemented. * Lots of icons and look and feel improvements for Free Swing basic and metal themes were added. Try running the GNU Classpath Swing Demo in examples (gnu.classpath.examples.swing.Demo) with: -Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel * Start of styled text capabilites for java.swing.text. * NIO FileChannel.map implementation, fast bulk put implementation for DirectByteBuffer (speeds up this method 10x). * Split gtk+ awt peers event handling in two threads and improve gdk lock handling (solves several AWT lock ups). * Speed up awt Image loading. * Updated TimeZone data against Olson tzdata2005l. * Make zip and jar UTF-8 "clean". * "native" code builds and compiles (warning free) on Darwin and Solaris. Runtime interface changes: * All native resource "pointers" in the VM interface classes are now exposed as gnu.classpath.Pointer objects. This might impact runtimes that optimize and support java.nio.DirectByteBuffers. Creating these classes and accessing the contents as void * pointers for the native reference JNI implementation is done through the JCL_NewRawDataObject and JCL_GetRawData functions. * Simplified the Class/VMClass interface. * Removed loadedClasses map from ClassLoader. It's now the VMs responsibility to manage the list of defined and loaded classes for each class loader. * Moved native methods from java.lang.reflect.Proxy to VMProxy. * Added hook to VMClassLoader to allow VM to do class caching. New Untested/Disabled Features: The following new features are included, but not ready for production yet. They are explicitly disabled and not supported. But if you want to help with the development of these new features we are interested in feedback. You will have to explicitly enable them to try them out (and they will most likely contain bugs). If you are interested in any of these then please join the mailing-list and follow development in CVS. * QT4 AWT peers, enable by giving configure --enable-qt-peer. * JDWP framework, enable by deleting the jdwp references from lib/standard.omit and vm/reference/standard.omit. No default implementation is provided. Work is being done on gcj/gij integration. * StAX java.xml.stream, enable by deleting the gnu.xml.stream and java.xml.stream references in lib/standard.omit. New in release 0.17 (Jul 15, 2005) * gnu.xml fix for nodes created outside a namespace context. * Add support for output indenting and cdata-section-elements output instruction in xml.transform. * xml.xpath corrections for cases where elements/attributes might have been created in non-namespace-aware mode. Corrections to handling of XSL variables and minor conformance updates. * DefaultMutableTreeNode preorder, postorder, depthFirst and breadthFirst traversal enumerations implemented. * JInternalFrame colors and titlebar draw properly. * JTree is working up to par (icons, selection and keyboard traversal). * JMenus were made more compatible in visual and programmatic behavior. * JTable changeSelection and multiple selections implemented. * JButton and JToggleButton change states work properly now. * JFileChooser fixes. * revalidate and repaint fixes which make Free Swing much more responsive. * Correctly handle system call interrupts and timeouts in native nio and net functions. * MetalIconFactory implemented. * Handle image loading errors correctly for gdkpixbuf and MediaTracker. * Added Tree World to GNU Classpath examples Free Swing demo. * FileChannel.lock() and FileChannel.force() implemented. * java.util.logging.FileHandler now rotates files. * Better handle GDK lock. Properly prefix gtkpeer native functions (cp_gtk). * Corba bug fixes and documentation updates. * Updated gcj build infrastructure. * Documentation fixes all over the place. See http://developer.classpath.org/doc/ * VM Integration Guide updates with a full section on VM/Classpath hooks. New in release 0.16 (Jun 30, 2005) * Better GTK scrollbar peer implementation when using GTK >= 2.6. * GdkGraphics2D has been updated to use Cairo 0.5.x APIs. * BufferedImage and GtkImage rewrites. All image drawing operations should now work correctly (flipping requires gtk+ >= 2.6) * Future Graphics2D, Image and Text work is documented at: http://developer.classpath.org/mediation/ClasspathGraphicsImagesText * Free Swing Top-Level Compatibility. JFrame, JDialog, JApplet, JInternalFrame, and JWindow are now 1.5 compatible in the sense that you can call add() and setLayout() directly on them, which will have the same effect as calling getContentPane().add() and getContentPane().setLayout(). * The JTree interface has been completed. JTrees now recognizes mouse clicks and selections work, but the visual implementation is not yet complete. Work on expansion and collapsing of the tree nodes is being implemented. * BoxLayout works properly now. * Fixed GrayFilter to actually work. * Metal SplitPane implemented. * Lots of free swing text and editor stuff work now. * When gtk+ 2.6 or higher is installed the default log handler will produce stack traces whenever a WARNING, CRITICAL or ERROR message is produced. * The CORBA implementation is now a working prototype that should support features up till 1.3 inclusive. We would invite groups writing CORBA dependent applications to try Classpath implementation, reporting any possible bugs. The CORBA prototype is interoperable with Sun's implementation v 1.4, transferring object references, primitive types, narrow and wide strings, arrays, structures, trees, abstract interfaces and value types (feature of CORBA 2.3) between these two platforms. The remote exceptions are transferred and handled correctly. The stringified object references (IORs) from various sources are parsed as required. The transient (for current session) and permanent (till jre restart) redirections work. Both Little and Big Endian encoded messages are accepted. The implementation is verified using tests from the former cost.omg.org. The current release includes working examples (see the examples directory), demonstrating the client-server communication, using either CORBA Request or IDL-based stub (usually generated by a IDL to java compiler). These examples also show how to use the Classpath CORBA naming service. The IDL to java compiler is not yet written, but as our library must be compatible, it naturally accepts the output of other idlj implementations. * New --with-vm-classes configure option, and new 'build' setting for --with-glibj. (Only for integrators.) Runtime interface changes: * Start of a generic JDWP framework in gnu/classpath/jdwp. This is unfinished, but feedback (at classpath@gnu.org) from runtime hackers is greatly appreciated. Although most of the work is currently being done around gcj/gij we want this framework to be as VM neutral as possible. Early design is described in: http://gcc.gnu.org/ml/java/2005-05/msg00260.html * Native method VMClass.getModifiers() now takes an additional boolean parameter. * Deprecated native method VMClassLoader.defineClass(ClassLoader, String, byte[], int, int) has been replaced by VMClassLoader.defineClass(ClassLoader, String, byte[], int, int, ProtectionDomain) * VMClassLoader.loadClass(String name, boolean resolve) is now native, replacing the former version which just returned null. * Deprecated native method VMClassLoader.getPrimitiveClass(String) has been replaced by new native method VMClassLoader.getPrimitiveClass(char). * Previously empty implementations of methods VMThread.countStackFrames(), VMThrowable.fillInStackTrace(), and VMThrowable.getStackTrace() have been removed; these methods are now native methods. * Fields "exceptionTypes" and "parameterTypes" have been removed from Contructor.java and getExceptionTypes() and getParameterTypes() are now native methods. New in release 0.15 (Apr 29, 2005) * The old character encoding framework (gnu.java.io.EncodingManager) has been replaced by a system based completely on nio.charset providers. Many converters have been added, both the io, lang and nio frameworks now use the same set of converters and the whole character stream framework (Readers and Writers) have been optimized. For some workloads this leads to 2x till 20x speedups. The default charsets supported are: Cp424, Cp437, Cp737, Cp775, Cp850, Cp852, Cp855, Cp857, Cp860, Cp861, Cp862, Cp863, Cp864, Cp865, Cp866, Cp869, Cp874, ISO_8859_1, ISO_8859_13, ISO_8859_15, ISO_8859_2, ISO_8859_3, ISO_8859_4, ISO_8859_5, ISO_8859_6, ISO_8859_7, ISO_8859_8, ISO_8859_9, KOI_8, MS874, MacCentralEurope, MacCroatian, MacCyrillic, MacDingbat, MacGreek, MacIceland, MacRoman, MacRomania, MacSymbol, MacThai, MacTurkish, US_ASCII, UTF_16, UTF_16BE, UTF_16Decoder, UTF_16Encoder, UTF_16LE, UTF_8, UnicodeLittle, Windows1250, Windows1251, Windows1252, Windows1253, Windows1254, Windows1255, Windows1256, Windows1257, Windows1258. Many more encoding are supported through the new IconvProvider depending on the platform iconv support. GNU libiconv is recommended. The IconvProvider is currently not enabled by default. To enable it define the system property gnu.classpath.nio.charset.provider.iconv=true. Some runtimes might choose to enable this by default by setting it through VMSystemProperties. We would like to get feedback on whether enabling or disabling the IconvProvider by default results in the highest speedups. * Free swing metal and pluggable look and feels have been improved. The GNU Classpath free swing example can now be run with different "skins" by setting the system property swing.defaultlaf to the GNU, Basic or Metal look and feel. * Some of the org.omg.CORBA classes and packages have now been implemented. The Savannah bug tracker contains additional tasks for which we are seeking help. * Fixed compatibility problems in the java.beans which affected Eclipse's Visual Editor Project. * New completely lock free (Inheritable)ThreadLocal implementation. * javax.swing.text.rtf framework added which can handle simple (plain) text tokens. * Support for parsing html files into Level 2 Document Object Model (org.w3c.dom.html2 and javax.swing.text.html.parser). And a start of javax.swing.text.html framework added. Runtime interface changes: * jni.h changed to better support compiling runtimes implementing jni; see VM integration guide for details. * New --enable-default-toolkit option to configure can be used to set the fully qualified class name of the default AWT toolkit to use. If not given, the old default of gnu.java.awt.peerk.gtk.GtkToolkit is used. * New --disable-core-jni option can be used to disable building the "core" JNI libraries. This is primarily useful if your VM can use the Gtk peers but not the core JNI libraries. * New system property "gnu.classpath.boot.library.path" can be specified to define the location of the JNI libraries. It is by all means meant ONLY for VM implementors and GNU Classpath hackers. See the hacking guide for more information. * The helper methods currentLoader() and allocateObject() for java.io.ObjectInputStream have been moved to a VMObjectInputStream class. Reference implementations are provided. * java.net.InetAddress now uses VMInetAddress for runtime/platform specific methods getLocalHostname(), getHostByAddr() and getHostByName(). java.net.NetworkInterface now uses VMNetworkInterface for runtime/platform specific getInterfaces() support. Default (Posix/GNU JNI) implementations are provided. * VMClass has a new method getModifiers(Class, boolean) which can be used to get the real modifiers for an inner class or the ones specified by the InnerClasses attribute. * All (possible) runtime specific methods of Object and Double are now in VMObject and VMDouble. Where possible generic reference implementations are provided. * The reference implementation of VMClassLoader now handles zip files on the boot loader class path in getResources(). Other changes: New in release 0.14 (Feb 25, 2005) * Character encoders and decoders have been added for: iso-8859-6 (arabic), iso-8859-7 (greek), iso-8859-8 (hebrew), iso-8859-9 (latin-5), iso-8859-13, iso-8859-15 (latin-9), cp1047 (ebcdic), ebcdic-xml-us,ascii, windows-1250, windows-1252, UTF-16BE (Big Endian), UTF-16LE (Little Endian), UTF-32BE (Big Endian), UTF-32LE (Little Endian). * Full documentation for all classes can be generated (again) by using the --with-gjdoc configure option. * javax.awt.imageio support through gdkpixbuf. Runtime interface changes: * VMSecurityManager has been replaced by gnu.classpath.VMStackWalker. currentClassLoader() is no longer needed, and there are also two new methods with non-native implementations. VM implementors are encouraged to provide more efficient versions. * VMRuntime.nativeLoad() now takes an additional ClassLoader parameter. New in release 0.13 (Jan 6, 2005) * The http url protocol handler has been replaced with a full HTTP/1.1 version from GNU inetlib. * A new ftp url protocol handler has been added also from GNU inetlib. * java.beans has been updated to 1.4 including support for XMLEncoder and XMLDecoder. * The java.util.Locale support is now based on the Common Locale Data Repository (CLDR) Project (see http://www.unicode.org/cldr/). GNU Classpath provides support for more than 250 locales now. This new support is experimental and the GNU Classpath hackers are working together with runtime developers and the unicode consortium to improve them in the future. If your runtime misdetects your locale or if the default locale gives problems please try running with -Duser.language=en and -Duser.region=US to fall back on a known good locale. * Added implementations of javax.xml (JAXP 1.3), org.xml.sax (SAX2) and org.w3c.dom (DOM Level 3) interfaces. It is possible to switch between different implementations AElfred2, GNU DOM, GNU XSL, libxmlj SAX, libxmlj DOM and libxmlj XSL by setting different system properties. Also provided is a preliminary XPath 1.0 implementation. The libxmlj versions are build around libxml2 and libxslt and have to be enabled during build time by the --enable-xmlj configure flag. The current support is equal to the last released GNU JAXP 1.3 release. These packages will be maintained as part of the GNU Classpath core classes in the future. For more information, conformance results and documentation on selecting different implementations see doc/README.jaxp. * More AWT accessible support. * AWT gtk+ peers component layout, dialog placement, keyboard focus handling and text positioning have been improved. * ImageIO interfaces are more complete. * JList, JTable and JTree have been hugely improved. * java.awt.Robot support with GdkRobot in the gtk+ awt peers. Needs XTest Extension (libXtst) XServer support. * New --disable-examples configure argument. Runtime interface changes: * Added a new method (VMRuntime.enableShutdownHooks) that enables the VM to lazily register an exit handler. * The java.lang.Class constructor now automatically sets the protection domain for array classes, based on the protection domain of the component type class. * New gnu.classpath.VMSystemProperties class. This replaces the system properties initialization in VMRuntime. Note that it is now the VMs responsibility to set one additional property: gnu.cpu.endian should be set to "big" or "little". * VMRuntime.nativeGetLibname() has been renamed to VMRuntime.mapLibraryName() and has only one argument, the name of the library. * String and StringBuffer now call VMSystem.arraycopy() directly and don't go through java.lang.System. Be careful to not initialize java.lang.System early in the bootstrap sequence in your VM runtime interface classes. * Some (wrong) documentation about the behavior of VMThread.sleep(0, 0) has been updated. Also, VMThread.sleep() now has a default non-native implementation, but it is a generic implementation that ignores the nano-seconds argument. Runtime hackers are encouraged to provide a more efficient version. * There is prelimenary support for nio direct byte buffers. See VMDirectByteBuffer. Please contact the GNU Classpath mailinglist when you add support for this to your runtime. New in release 0.12 (Nov 14, 2004) * GNU Classpath's JAR implementation now has preliminary support for signed entries, for so called "signed JAR" file support. Signed JAR files are one of the key security features of managed runtimes, and allows code to run privileged given unforgeable proofs of identity. * A much improved version of X.509 certificates has been added, including a robust certificate path checking algorithm. Also included is an implementation of the RSA signature scheme. * Full java.awt.color implementation, with all standard ICC profiles, except for PhotoYCC color space. * java.beans 1.4 updates and bug fixes. * java.awt.image support updated to 1.4. * Improved build process. Uses less memory with gcj and C code is buildable with -Werror on most platform. Please configure with --enable-Werror and report any remaining issues. * Big-endian (PowerPC) fixes for native awt GTK+ peers. * Checkstyle support, see scripts/checkstyle-config.xml. * Better AWT focus management fro GTK+ peers. * Much faster and better fonts support (for both gdk Graphics and cairo Graphics2D) * AWT Choice fixes for hidden components. * HTTP Connection Handler fixes for POST support. * Much fuller collection documentation. * Lots of Calendar bug fixes. * More javax.imageio support. * Better AWT Help MenuBar support. * Lookahead support for regular expressions. * Serialization object stream fixes for multiple ClassLoader scenarios. * Swing TabbedPane, ColorChooser and ComboBox improvements. * Start of JTree functionality. * Improved Eclipse 3 support for GNU Classpath based runtimes. Runtime interface Changes: * New --enable-java-lang-system-explicit-initialization configuration option. (Warning, will be replaced in next release, please consult the mailinglist.) * The reference implementation of VMClassLoader has default implementations for getResource(s) and provides support for a new default getSystemClassLoader implementation. New in release 0.11 (Sep 13, 2004) * javax.swing.Spring and SpringLayout support. * Added pluggable look and feel support for BasicTextFieldUI and BasicToolBarSeparatorUI. * java.swing.text support for (Default and Layered) Highlighter, FieldView, PlainView, TabExpander and TabableView added. * Start of JTable and JTree implementation. * Internal Swing frames work. * JMenu and JPopupMenu work. * New gtk+ AWT FileDialog peer now based on gtk+2.4 or higher. * java.awt.image LookupTables and kernel support. * Improved java.awt.image.BufferedImage support. * AWT 1.0 event model support. * GNU Classpath now comes with some example programs (see examples/README). * New javax.crypto, javax.crypto.interfaces, javax.crypto.spec, javax.net, javax.net.ssl, javax.security.auth, javax.security.auth.callback, javax.security.auth.login, javax.security.auth.x500, javax.security.sasl and org.ietf.jgss packages are now officially part of GNU Classpath. Extra crypto algorithms can be obtained from the GNU Crypto project, a full TLS implementation is provided by the Jessie project. http://www.gnu.org/software/gnu-crypto/ http://www.nongnu.org/jessie/ * Frame.setIconImage() support. * AWT GDKGraphics scaling. * New configure flag --enable-gtk-cairo to build Graphics2D implementation build on cairo and pangoft2. Enabled at runtime by defining the system property gnu.java.awt.peer.gtk.Graphics=Graphics2D. * javax.swing.JSpinner implemented. * Extensive documentation update for java.util collection classes. * java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented. * GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and tool integrators are encouraged to directly integrate GNU JAXP. This release has been tested against GNU JAXP 1.1. http://www.gnu.org/software/classpathx/jaxp/jaxp.html * JColorChooser, JComboBox and JTextField implemented, including example uses in GNU Classpath Examples swing Demo. Runtime interface Changes: * java.lang.Compiler now uses the new java.lang.VMCompiler; there is a reference implementation that most VMs can use. * java.lang.VMSystem has a new getenv(String) method and a reference C/JNI implementation that should work on most Posix like systems. * java.util.TimeZone has been split into a platform independent class and a platform dependent class VMTimeZone. GNU Classpath comes with a generic way to get at the default time zone for Posix/GNU-like platforms. * [VM]AccessController improvements. In particular it handles `doPrivileged' calls better, and allows for recursive `doPrivileged' calls in the same Thread. (see vm/reference/java/security/) New in release 0.10 (Jul 9, 2004) * java.net.URL now uses application classloader to load URLStreamHandlers and reuses URLStreamHandlers when URL is reset (but protocol isn't changed). * java.io.File.deleteOnExit() implementation. * java.text multiple new features and bug fixes (only 2 out of the 1000+ java.text Mauve tests now fail). * Better (non-black) default AWT System colors. * AWT lists use GTK treeviews. * Proper AWT focus management has been implemented. * Swing menus and scrollpanes are beginning to work. * Swing splitpanes, dialogs and internal frames were added. * Swing repainting / double buffering was redone. * Font management and Pango DPI conversion fixes. * A lot of AWT imaging and event bugs have been picked out. * More of javax.swing.text has been implemented. * javax.swing.Timer has been reimplemented. * java.security.AccessController has been implemented (see runtime section). * The default java.lang.SecurityManager now uses AccessController. * New java.beans.Statement and Expression implementations. * Small FileChannel implementation speed improvement for traditional JNI based systems. * Regenerated all included JNI header files with gcjh (3.5 CVS), removes extra extern modifier and allows stricter compiler warning. * More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and -Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes, made it compilable with C++ compilers and jni.h got renamed from jni.h.in). * Double.toString() and Float.toString() now work properly on 64-bit PowerPC systems. * PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes. * Build system refactored and removed old Japhar specific support. * The gnu.java.awt.EmbeddedWindow class has been improved, and now supports embedding AWT windows in other top-level X windows. This functionality is required by gcjwebplugin. * gcjwebplugin, an applet viewer that can be embedded into several web browsers, has been extensively tested with this release of classpath. (See http://www.nongnu.org/gcjwebplugin/) * Runtime environments based on GNU Classpath 0.10 should be able to start up Eclipse 3.0 out of the box now. Runtime interface Changes: * VMProcess.destroy() default implementation fixes. * Fixed the "portable native sync" code; it had been broken since Classpath release 0.06, when we upgraded to GTK+2. Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses the platform's native threading model -- pthreads in most cases. If the Java runtime doesn't use the native threading model, then you should specify --portable-native-sync when configuring Classpath, so that GLIB will use the Java threading primitives instead. (For a superior alternative, see below.) * The VM can set the system property gnu.classpath.awt.gtk.portable.native.sync instead of using the --portable-native-sync configure-type option. See doc/vmintegration.texinfo for details. * We intend that the next release of GNU Classpath will require the VM to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for one JNI 1.2 function: GetEnv(), in the JNI Invocation API. If this poses problems, please raise them on the classpath mailing list. * The reference implementation of VMThread.holdsLock(Object) now has a default implementation written in java. For efficiency and to prevent spurious wakeups a real 'native' runtime version can be supplied. * There is a new java.security.VMAccessController class that runtimes need to implement to properly support SecurityManagers. The default implementation that comes with GNU Classpath makes sure that ANY attempt to access a protected resource is denied when a SecurityManager is installed. Which is pretty secure, but also no very useful. Please see the documentation in vm/reference/java/security/VMAccessController.java, and please give feedback on the GNU Classpath mailinglist whether or not the current AccessController framework is flexible enough. New in release 0.09 (May 2, 2004) * Includes updated GNU JAXP version from 2004-02-01. * Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean. * java.io is now implemented by delegating most tasks directly to java.nio. * Reworked/Optimized implementations of java.nio.Buffer and subclasses. * New javax.print, javax.print.attribute[.standard] and javax.print.event packages and classes. * java.text attributed iterators support. * New javax.imageio, javax.imageio.event and javax.imageio.spi packages and classes. * GNU Classpath can now load service providers that are described via META-INF/services/* resources in extension JARs. This is useful for implementing the various APIs that are supposed to be extensible via custom plugins. For details, please see the documentation of gnu.classpath.ServiceFactory. Application developers are strongly discouraged from calling glibj internal packages. Instead, they might want invoke the newly implemented javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard method for loading plug-ins. * New developers wanting to help the GNU Classpath project might want to review the greatly expanded Hacker Guide included in the doc directory or online at http://www.gnu.org/software/classpath/docs/hacking.html Also the FAQ has been expanded. And when working from CVS you can now use a simple autogen.sh script to get all autotools magic done automagically. * New configure option --with-glibj which defines how to install the glibj class files as zip, as flat directory files or both (zip|flat|both) [default=zip]. When working with multiple runtimes some of which might not support bootstrap classes in zip files the --with-glibj=both option is recommended (this does take extra disc space). * Two big code drops from the libgcj gui branch updating various java.awt and javax.swing classes. * Multiple java.net.InetAdress fixes and java.rmi fixes. * ServerSocket.accept() now restarts listening when system call interrupted. * Much cleanups to make standard API doc valid XHTML (not completed yet). * A scan for unused variables and non-static invocation of static methods turned up a couple of subtle bugs which have now all been fixed. * The Mauve testsuite has been cleaned up considerable and lots of issues in the GNU Classpath core class implementation have been fixed. VM Interface changes: * java.lang.Class/VMClass interface was changed. The interface now no longer requires an instance of VMClass for each Class instance. Instead the field vmdata in Class is now of type Object. * GNU Classpath now assumes that JNI calls SetXField can modify final fields. This was previously used silently for System.in/out/err and should be considered as a feature now. * A new VMProcess and a sample JNI C implementation are now provided to make Runtime.exec() work out of the box on some systems. This requires a small change to VMRuntime.exec() when a runtime wants to use it as the default java.lang.Process implementation. * The implementation of most of java.io through java.nio moved serveral runtime specific I/O methods. Most methods do have a generic default native C JNI implementation in native/jni/java-nio. * Runtime support methods for java.io.File have been moved to VMFile which also comes with a default JNI C implementation. * To support the new service provider mechanism runtimes must make sure that extension JARs are made accessible via the default context class loader. New in release 0.08 (2004/12/03) * java.util.regexp implementation through gnu.regexp wrappers. * java.net.URI implementation. * Working implementation of javax.swing.undo. * java.awt.geom.CubicCurve2D/QuadCurve2D: Can now solve cubic and quadratic equations; implementation adapted from the GNU Scientific Library. * Lots of java.awt and gtk+ peer improvements. Also more Swing work. Start of EmbeddedWindow support. * BufferedReader speed improvements. * Improved useabilty of java.text implementation for several applications. * ObjectInputStream is much faster and more compatible with other implementations. * Fix handling of alias methods, where a method has been deprecated in favour of a new one with the same funtion but a different name. (See Deprecated Methods section in the GNU Classpath Hacking Guide.) * javax.print.attribute.standard added. * Lots of java.nio, java.net, java.io * Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+. VM Interface changes: * Split native methods in java.lang.Runtime into java.lang.VMRuntime. * Resources are now also loaded/needed through the bootstrap classloader (gnu.regexp needs MessageBundle included in glibj.zip Fixed Classpath bugs: #6095 java.awt.geom.QuadCurve2D.solveQuadratic sometimes gives wrong results #7099 EventListenerList.getListenerCount should accept null argument #7104 EventListenerList.add does not work #7105 EventListenerList.remove does not work #7107 DefaultBoundedRangeModel.setValue and friends should not throw And lots more. New in release 0.07 (2003/30/11) * Works with libtool 1.5 (and 1.4.3). * java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango. Lots and lots improvements on the peers. * java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D: Subdivision and flatness calculation implemented. * java.awt.geom.FlatteningPathIterator: Working implementation. * gnu.java.awt.BitwiseXORComposite helper class. * New rmic compilers (jikes, kjc) support. * java.text bug fixing and 1.4 updates (Currency). * Hashtable and HashMap function more similar to other implementations. * javax.naming and java.beans classloader fixes. * URL parsing, URLConnection, protocol and (needed) permission fixes. * More java.nio implementation (API complete, but implementation not finished yet). * Lots of java.net code cleanup. * Improved documentation. * Numerous bug fixes in almost every package, and lots of updates for 1.4 functionality. * Fixed Classpath bugs: #2944 Incorrect synchronization in java.util.logging.ErrorManager #6075 java.awt.geom.GeneralPath.getCurrentPoint returns wrong results #6076 java.awt.geom.GeneralPath constructor sometimes hangs #6089 java.awt.geom.GeneralPath.getPathIterator does not work [...] VM Interface changes: * Thread has been split in a VM-independent Thread class and a VM-dependent VMThread class. New in release 0.06 (2003/22/08) * Update java.awt peers to GTK+2. * java.awt.GridBagLayout implementation. * javax.swing.border implementation. * java.security and java.security.cert updated to 1.4 spec. * New JNI native target code layer. See native/target/readme.txt. * --enable-regen-headers configure flag for automatic jni .h file generation. * Removed workaround for gcj 3.2 and lower, gcj 3.3+ or jikes 1.18+ is now needed for compiling. * Lots of improvements and/or new classes for java.awt, java.awt.dnd, java.awt.font, java.awt.geom, java.awt.image, java.io, java.math, java.net, java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf, javax.swing.text. VM Interface changes: * VMClassLoader.loadClass(), the bootstrap classloader called by Class.forName() and ClassLoader.loadClass(), may now return null when a class is not found instead of throwing a new ClassNotFoundException. This is a performance optimization in some cases. This also changes the Class.forName() reference code. * Native methods in Class have been moved to VMClass. A few additional methods are also available in VMClass to provide optional performance improvements. * A VM can now supply its own String.intern() strategy through the VMString class. The supplied VMString reference class implements the original WeakHashMap strategy. * Float and Double to/from bits conversion functions can now be supplied by the VM through VMFloat and VMDouble. Default JNI conversion methods are supplied. New in release 0.05 (2003/02/15) * Supports free Java VMs Jikes RVM and Kissme out of the box, perhaps others. * Supports GNU Crypto 1.1 as the official provider of cryptographic primitives and tools for GNU Classpath, available separately from http://www.gnu.org/software/classpathx/crypto/crypto.html. * Supports GNU Classpath Tools sub-project of GNU Classpath, official provider of standard tools such as gjdoc, a javadoc replacement, and others. Future releases of GNU Classpath will begin to include these tools, available separately from http://www.gnu.org/software/cp-tools/. * Java primitives can be used to support AWT native threading, see the --enable-portable-native-sync configure option which may become the default in a future release. * Include file jni.h has been updated to the 1.4 specification. * VM specific internal types for jobject, jfieldID, and jmethodID are supported in jni.h. More details can be found by reading the comment in include/jni.h.in. By default the old definitions are used instead. * New VM helper class java.io.VMObjectStreamClass which should provide the hasClassInitializer() method. Previously ObjectStreamClass used Class.getDeclaredMethod("") but according to the spec this should always throw NoSuchMethodException for class initialization methods. A JNI reference implementation is provided as vm/reference/java-io/java_io_VMObjectStreamClass.c * There have been numerous infrastructure improvements * Configure option --enable-gjdoc to generate javadoc-like output * Gjdoc output is included with distribution, see doc/api/html/ * DESTDIR fully supported for install and uninstall * Runtime.execInternal contract changed to allow for null `env' and to accept `dir' argument. * VMObject.getClass() removed. It was never used. * java.lang.Throwable is now a 'normal' GNU Classpath class that uses the VM specific java.lang.VMThrowable to get at the VM state and (if needed) the StackTraceElements for a particular exception. A default implementation (that does nothing) is provided in vm/reference/java/lang/VMThrowable.java. * The vm/reference classes from the gnu.vm.stack and their counterparts ExecutionStack and StackFrame in gnu.java.lang have been removed since they are not actually part of the VM interface anyway. * The GPLed com.sun.javadoc classes have been moved to the gjdoc application from the GNU Classpath Tools project. See for more information the homepage at: . New in release 0.04 (2002/05/05) * Additional configure options to disable zip creation and installation as well as disable gtk peer native compilation. * Addition of java.nio, java.util.logging, and javax.swing. * Integration of most or all of the ORP patches to date, the purpose of which are to make it possible to use JBOSS with ORP and Classpath. This is still in a testing phase however. * Significant changes in the reference VM interface that may require support from the JVMs. * Lots of bugfixes. New in release 0.03 (2002/02/08) * More merges with libgcj have been performed including java.math which now provides a pure Java implementation of that package. Current status at * A pure Java implementation (Jazzlib) of java.util.zip is available. * Added the java.rmi implementation that Transvirtual donated to the FSF. * Includes jni.h now, eliminating the need to specify a particular VM via configure. * No proprietary classes or programs are required to compile. Compiles out of the box with jikes or gcj. * Separation of compiling Java source and native libraries through the configure mechanism. If given no arguments, configure will setup the subsequent build to only produce Java bytecode (.class files). More information is available in INSTALLING. * Support for compiling in a separate directory, as an example you may cd classpath-0.03; mkdir build; cd build; ../configure; make * Works with Orp 1.0.9 out of the box. Build instructions can be found at * Lots of bugfixes that were found by using Classpath with the gcj, Orp, SableVM, KissMe and Jaos VMs. Please use our bugdatabase at * Lots of updates to make Classpath more compliant with the 1.2, 1.3 and 1.4 API specification. The current status can be found at * All files are now distributed under the same terms. Added clarification to GPL exception. New in release 0.02 (2001/01/06) * Support for printing exceptions with Japhar 0.09 + patch included in resource/japhar-0.09.patch.1. * Typos, assorted bugfixes. New in release 0.01 (2000/11/20) * More packages are included now, though many remain untested. * Support for Japhar 0.09 included. New in release 0.00 (1999/02/01) * First official development release of clean room class library for Java * Following packages included: -- java.beans -- java.io -- java.lang -- java.lang.reflect -- java.math -- java.net -- java.security (partial and non-functioning) -- java.security.acl -- java.security.interfaces -- java.util * Code is mostly Java 2 (see JDK 1.2) compatible with some functionality missing and/or untested. * Support for Japhar (http://www.japhar.org/) virtual machine is included. Requires the current Japhar from CVS. * Extensive javadoc comments for public API included * Licensed under the GNU Library General Public License (see COPYING.LIB) * Does not depend on any non-free code - developed in a "clean room" environment.
