	* gnu/java/rmi/server/RMIObjectInputStream.java (resolveProxyClass):
	Expect that proxy interfaces may have different class loaders.
	* gnu/java/rmi/server/UnicastServerRef.java: Rewritten.
	* java/rmi/registry/Registry.java,
	* java/rmi/server/UnicastRemoteObject.java:
	Documented about proxy stubs.
	* gnu/java/rmi/server/CombinedClassLoader.java,
	java/rmi/server/RemoteObjectInvocationHandler.java: New files.
	* NEWS: Added entry.
