Description tbrunhoff 2009-02-04 02:49:10 UTC
After running a (long) c++ app for a couple of minutes, it hit a break point.  I left it at that breakpoint and poked
around off and on for about two hours.  During the final session of poking, the ide locked up. The attached jstack
output shows a deadlock. If there is some tool I can use to get more info, I'll leave the ide the way it is until
perhaps tomorrow mid morning (4 Feb 2009 10am PST).

I don't think that NetBeans code is the guilty in this deadlock. Jesse, please could you verify that. Thanks.

It would look to be a bug in AWT - various Frame methods synchronize on Frame.this rather than using the AWT lock.

I don't think the project system is involved. It just calls Frame.setTitle on the AWT thread.

looks like jdk bug:
Comment 8 Jesse Glick 2009-02-11 15:36:59 UTC
OK. Be sure to put 'netbeans' in the keyword field and best to mention this bug report in a comment.
