I managed to find a very similar sounding bug that is from year 2012 but it was iced-tea specific: http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=857
Solution there was to make sure that setLookAndFeel call happens before any other call to swing. But I have no idea how that could be related to this bug. Only similarity is that atk-wrapper seems to trigger bugs in java UI code. Possible completely different issue.

Since I have reproduced this issue these two completely different codebases, I am moving the bug further upstream. The original Netbeans bug report can be viewed here: https://netbeans.org/bugzilla/show_bug.cgi?id=256124 Essentially, during routine interaction and calling of various AWT methods, somewhere between 8u45 (15.04) and 8u66 (15.10), something broke causing the application to hang intermittently when these methods are called. Some sample jstack traces are attached, the issue should be fairly obvious to spot.
