Comment 2 Petr Cyhelsky 2013-04-22 14:00:20 UTC 
it seems the fix doesn't work
Comment 3 Milutin Kristofic 2013-04-22 15:50:49 UTC 
Fix works. This is another issue, where jeditorPane adds AncestorListener. It creates AncestorNotifier with JeditorPane. It's added to parent class of FontAndColorsPanel (JPanel) and it is never removed.

I am removing it in removeNotify method.
