Hi all,
I recoded my server program to use java.nio and it works fine.
When I try to close socket:
  serverSocket.socket().close();
  boolean b1 = serverSocket.socket().isBound();
  boolean b2 = serverSocket.socket().isClosed();
and check values, b1 is true and b2 is true.
When I run netstat I see that state od port is "LISTENNING"
While I was using "old" IO, closing socket did excatly what I expected (netstat did not list port as Listenning).

How can I "unbind" socket without shuting down JVM?

Try closing the channel it self instead of its associated socket, like:

ServerSocketChannel serverSocket ...;
serverSocket.close();

I think that will help, because closing the socket only has to be done when using the old I/O-package. ServerSocketChannel's besides being closed also have to be decoupled from the Selector, which will not be done, when using the code:

serverSocket.socket().close();
