SocketFactory missing close(ServerSocketChannel)

JGroups SocketFactory contains methods for creating named ServerSocketChannels, however, there is no corresponding close(ServerSocketChannel) method.
WF relies on the SocketFactory to register JGroups sockets with its SocketBindingManager, so that the management layer can report which sockets are connected, to which address/port are they are bound, etc. The close(...) methods are necessary to unregister from the SocketBindingManager.
