	(serverSocket): Made it a NIOServerSocket.
	(impl): Removed.
	(ServerSocketChannelImpl): Initialize only serverSocket.
	(initServerSocket): Removed.
	(getNativeFD): Rewritten.
	(implConfigureBlocking): Set socket timeout and removed comment.
	(accept): Rewritten.
	* gnu/java/nio/SocketChannelImpl.java
	(impl): New variable.
	(connected): Removed.
	(SocketChannelImpl): Initialize impl too.
	(getImpl): New method.
	(isConnected): Rewritten.
	(read): Rewritten, set position in buffer correctly.
	(write): Set position in buffer correctly.
	* java/net/ServerSocket.java (getImpl): New method.
	* gnu/java/nio/NIOServerSocket.java,
	gnu/java/nio/natNIOServerSocket.cc: New files.
	* gnu/java/nio/natServerSocketChannelImpl.cc: Removed.
	* Makefile.am
	(ordinary_java_source_files):
	Added gnu/java/nio/NIOServerSocket.java.
	(nat_source_files):
	Removed gnu/java/nio/natServerSocketChannelImpl.cc
	and added gnu/java/nio/natNIOServerSocket.cc.
	* Makefile.in: Regenerated.
