Description Marek Fukala 2008-08-06 10:32:00 UTC 
When trying to reproduce issue 142910 I run into a deadlock. Threaddump is attached. 

This is a problem of the editor braces matching infrastructure always calling BracesMatcher.findMatch() under document
readlock. I need to access the parser via Source.runUserActionTask() which is however forbidden under document readlock. 

There are duplicate issues #134046 (P2), #137343 (P1) and #131060 (P1). They were mostly closed as duplicates of issue
#131284. The last one was partially fixed and closed.

Now it seems that even after fix of issue #131060 the probability of the problem to happen is not insignificant.

Marku, could you please review my changes in HTMLBracesMatcher in http://hg.netbeans.org/main/rev/4f9dc43334c1. They
should fix this problem. Thanks
