Trying to write a program, where in The current thread tries to close the Singleton Socket Connection that was created earlier. My singleton Socket is running on a
JBoss Server, I have a client which is run to do the necessary job on the server by invoking a program through JBoss remoting.
The problem is that the program I run to close the socket does not return, but is waiting for the Socket handle.

The code is attached.

no, I mean dump *all* threads. It sounds like you have a deadloack so you need to see what thread is holding the lock
