I got deadlocks during external modification of file and reloading it in editor. I had ImageViewer.java opened in emacs and IDE and I was doing modifications in emacs - syntax errors. Then I was changing focus to editor by Alt+tab and after doing it couple times (cca 4 times) IDE stopped responding. Happened in two folowing IDE sessions, then I'm not able to reproduce again. Happened with patches from: http://www.netbeans.org/issues/show_bug.cgi?id=35914 http://www.netbeans.org/issues/show_bug.cgi?id=33165 http://www.netbeans.org/issues/show_bug.cgi?id=14803 http://www.netbeans.org/issues/show_bug.cgi?id=35930

I haven't modified the file in IDE editor.
From the deadlocked threads it seems that the tooltip popup code was involved. I've tried to invoke debugger and place a mouse over a variable and then write file in external editor and then quickly switch back to ide and move a mouse cursor a bit so that tooltip code gets triggered. Unfortunately the file was always reloaded before the tooltip timer triggered. I'll try to fix the problem.
This issue was related to particular version of the fix of issue 33165 and should no longer appear with the final version of that fix.
Didn't happen recently. Verified.
