Subject: 2006-03-24  Audrius Meskauskas  <AudriusA@Bioinformatics.org>

	* gnu/java/rmi/activation/ActivationSystemTransient.java:
	Inherit from Activator.

2006-03-24  Audrius Meskauskas  <AudriusA@Bioinformatics.org>

	* gnu/java/rmi/activation/DefaultActivationGroup.java (newInstance):
	Print debug message if debug flag is set.
	* gnu/java/rmi/activation/DefaultActivationSystem.java: Rewritten.
	* gnu/java/rmi/server/ActivatableServerRef.java (activate): assign
	detail, do not call iniCause(). (exportClass): New method.
	* gnu/java/rmi/server/CombinedClassLoader.java (constructor):
	Ignore null (bootstrap) class loader.
	* gnu/java/rmi/server/UnicastServerRef.java (methods, skel, stub,
	buildMethodHash, findStubSkelClass, getHelperClass): Changed
	visibility to protected.
	* java/rmi/activation/Activatable.java (export, register): Rewritten.
	(toStub): New method.
	* java/rmi/activation/ActivationGroup.java (getSystem): Rewritten.
	* java/rmi/activation/ActivationSystem.java (SYSTEM_PORT):
	Explained property java.rmi.activation.port.

Applying two patches toghether because the intermediate version does not build.
