Description _ gtzabari 2011-02-04 01:54:53 UTC 
Netbeans 7.0 dev build 201101140000
JDK 1.6.0_23-b05

Netbeans deadlocks on me fairly frequently when code-formatting a large class file. I've attached a thread-dump for your review.

Comment 2 _ gtzabari 2011-02-04 01:56:54 UTC 
By the way, Netbeans was "scanning for external changes" while I invoked code-format. It's possible that the two are waiting on each other to finish. Just a guess.

Comment 4 Vladimir Voskresensky 2011-02-04 13:47:43 UTC 
FYI, in issue #195066 there were no any scanning activity

I think the problem is due to incorrect impl of ActionFactory.FormatAction.
line 1713 calls 
target.setCursor(origCursor)
which is access to swing object. and due to use of 
ProgressUtils.runOffEventDispatchThread => passed Runnable is redirected and access AWTTreeLock from non EDT
