Comment 1 pzajac 2003-09-22 13:01:29 UTC

Exception is thrown in swing code. Reassigned to core/windows.

Comment 2 mslama 2003-09-22 13:12:16 UTC

No NB code in exception call stack. It looks like JDK bug. Please
search bug database at java.sun.com. If you do not find anything you
can file new bug there against JDK. Looks like issue
