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.
