You should not try to make a network connection in such a method. Better is to mark the panel temporarily invalid,
displaying an icon, test the URL in the background, and asynch mark it valid when complete.

Currently WS Client Panel is realized via Async validation.
As result validation is done in the separate thread ( not AWT ).
