Proprietary VMs put their libjawt.so + implementations in VM-specific directories but search /usr/lib first. + If GNU Classpath's libjawt.so is installed in /usr/lib it will create + problems for people who use a proprietary VM to run AWT Native + Interface applications. +* The GdkGraphics2D backend has been made the default. There is no + longer an explicit dependency on Cairo, the --enable-gtk-cairo + configure option is gone, and GTK 2.8 or higher is now required to + build the GTK peers. +* A Mozilla plugin, 'gcjwebplugin', is now included. It introduces a + dependency on the Mozilla plugin support headers and libraries. +* New java implementations of png and gif imageio readers and writers. +* A tools.texinfo document has been created and now includes + documentation about: + * appletviewer + * gcjwebplugin + * jarsigner + * keytool +* Several new tools are now included: + * appletviewer + * jar + * native2ascii + * serialver + * keytool + * jarsigner + A new configure option --enable-tool-wrappers causes wrapper + binaries to be built for VMs that support the JNI Invocation API. +* javax.sound.midi providers have been added to read and + write standard MIDI files. +* A javax.sound.sampled .au and .wav file readers have been added. +* New Java Virtual Machine Tool Interface header, jvmti.h. +* AWT peers for X Windows based on Escher (a pure java X protocol + implementation) have been added. So far it supports AWT 1.1 style + Graphics, image loading via ImageIO (PNG, GIF and BMP images in this + release), top level components as well as mouse and keyboard input. + It is capable of running many Swing applications. Graphics2D and + AWT widgets are not yet supported with this peer set. +* GConf based util.peers backend (see the --enable-gconf-peer and + --enable-default-preferences-peer configure options). +* Support for batch importing trusted certificates for use with ssl + connections (see script/import-cacerts.sh). +* NIO scatter-gather channel support. + +Runtime interface changes: + +* A new class, VMURLConnection, is used to implement + URLConnection.guessContentTypeFromStream. The reference + implementation uses libmagic (and falls back to doing nothing if + libmagic is not available). +* The method gnu.java.io.PlatformHelper.toCanonicalForm() has been + replaced with a JNI implementation of VMFile.toCanonicalForm() for + GNU/Posix systems. +* A new class, VMRuntimeMXBeanImpl, is used to implement + the low-level support of the runtime management bean. + VMs should use it to supply the input arguments and start + time of the VM. In addition, one of sun.boot.class.path + or java.boot.class.path should be defined by the VM to + support the optional boot class path access functionality. +* The Unsafe class was moved back to the place expected by the JSR 166 + reference implementation. We've also added a couple other new VM + classes to support the JSR 166 code -- sun.reflect.Reflection and + sun.reflect.misc.ReflectUtil. +* Another new class, VMClassLoadingMXBeanImpl, is used to implement + the low-level support of the class loading management bean. + VMs need to supply it with information about how many classes + are currently loaded, how many have been unloaded and whether + verbose class loading output is on or off. Provision should also + be made for the latter to be toggled at runtime. +* VMThreadMXBeanImpl is used to implement the low-level support + of the thread management bean. Providing this interface requires + providing a fair amount of information about threads, including + optional time and contention monitoring, and instances of the + new ThreadInfo class in java.lang.management. getState() has also + been added to the VMThread interface; this is required by the bean + as well as java.lang.Thread. +* VMMemoryMXBeanImpl is used to implement the low-level support + of the memory management bean. Providing this interface requires + providing information about the levels of heap and non-heap memory, + and the number of objects eligible for garbage collection. +* VMCompilationMXBeanImpl is used to allow for optional compilation + time support for Just-In-Time compilers. +* VMMemoryPoolMXBeanImpl is used to implement the low-level support + of the memory pool beans. Providing this interface requires + providing memory usage statistics for each supported bean. +* VMManagementFactory provides the names of the memory pools, + memory managers and garbage collectors maintained by the virtual + machine. These are used to create the beans by the ManagementFactory. +* VMMemoryManagerMXBeanImpl and VMGarbageCollectorMXBeanImpl provide + low-level support for memory managers (including the specific subclass + of garbage collecting memory managers). The interfaces for these + require no more than enumerating the number of collections and the + time spent (for garbage collectors) and a relationship to the memory + pools (for all), along with a validity check. + New in release 0.91 (May 15, 2006) * Experimental activation (java.rmi.activation) support, including RMI |
