Comment 1 Martin Entlicher 2013-04-25 16:27:37 UTC 
My action is waiting for the lock, thus it did not cause the deadlock.
Parsing should not wait in AWT for locks held by other threads.
Comment 2 Theofanis Oikonomou 2013-05-28 14:09:33 UTC 
I cannot tell what version you are using but the parsing outside of EDT should be already fixed by http://hg.netbeans.org/main-golden/rev/7cbe1576bbb0. Please try a latest build and reopen if it still happens for you. Thank you
