Description fabriziogiudici 2009-07-09 13:24:39 UTC 
While I was *possibly* working with Subversion, NetBeans froze completely. Inspecting with JConsole revealed the AWT
Thread blocked on a lock. The thread owning the lock in turn is waiting for another lock.

The application is frozen since 10 minutes now, and I have to kill it.

Comment 3 mslama 2009-07-13 11:31:58 UTC 
Missing build number. For now I will check 6.7 FCS sources.
Comment 4 fabriziogiudici 2009-07-13 12:18:08 UTC 
Yes, it was 6.7 FCS.
Comment 5 mslama 2009-07-13 13:58:43 UTC 
I will attach proposed patch. Fix takes ProjectManager.mutex lock before CodeStylePreferences internal lock to avoid
deadlock.

Use ProjectManager.mutex().readAccess before internal CodeStylePreferences lock to fix deadlock.
