*** This bug has been marked as a duplicate of bug 210279 ***
Comment 3 _ wadechandler 2013-05-01 17:59:26 UTC 
This is not a duplicate. This is caused by Nimbus and thread safety and NB not following the Swing guidelines. This should at least be looked at to determine if it can be solved. This still affects at least 7.2.1, and I imagine 7.3, but have yet to confirm that. I can cause this to happen in the NB IDE 7.2.1 and an RCP app using 7.2.1 platform. There should be some way to annotate a class to have the system spawn off to the EDT with invokeAndWait or invokeLater with a callback to cause the thread to wake backup and continue working.

Actually the original bug was a duplicate of #210279

Only this report points to problem with Nimbus l&f: http://statistics.netbeans.org/exceptions/exception.do?id=589094
And that particular case is fixed in core-main 7f26464bc0de
