Description Marian Petras 2009-07-13 07:45:16 UTC 
The IDE got locked while attaching to a second instance of NetBeans.

Apparently, the deadlock was caused by scheduling a task using EventQueue.invokeAndWait(...). The task cannot be
finished until the thread that scheduled it relieves a lock. But the lock cannot be relieved until the scheduled task
finishes.

See the attached thread-dump.
