Description Zom-B 2014-10-07 12:42:17 UTC 
100% Reproducible deadlock occurs between "General Timer Thread" and "AWT-EventQueue-1" when dragging a layout manager from any container to any another container and dropping it there (regard less of whether the other container already has a layout manager, or "Free Design").

Comment 3 Tomas Pavek 2015-09-18 16:09:50 UTC 
This is a bug of com.brightsight.chart timer thread that calls Swing (JPanel.updateUI()) out of AWT event dispatch thread, moreover taking a lock before that.

We cannot do anything with this in GUI builder, it is a bug in a custom component/library that spawns its own timer thread and then calls Swing in it under a lock.
