The described exception is a problem in JDK, see http://bugs.sun.com/view_bug.do?bug_id=6739738
We will try to implement some workaround to avoid the exception.
Comment 3 Jan Stola 2009-07-15 15:25:24 UTC 
I have implemented a workaround. The border is not set if border.getBorderInsets(comp) == null (e.g. in the buggy 
case). I wasn't able to verify the fix on my Windows machine (the issue doesn't occur on Windows). Hence, feel free to 
reopen this issue if the workaround doesn't work for any reason.
