@hanm Not exactly.
The test case is about reconfig the server to a port which is unavailable
(blocked). Steps:
1) Bind the server to "oldClientPort"
2) Bind "newClientPort" with custom socket
3) Reconfig the server to bind "newClientPort" - fails
4) Check if "oldClientPort" has become available
...
Step 4) fails, because of the aforementioned reason: reconfig fails to bind
the port, throws exception, but exception handler doesn't close the selector,
only the socket.
I do things in swapped order: close the thread and socket first, then try
to bind the new port.
