Comment 1 Jan Becicka 2009-11-06 10:30:38 UTC 
this exception simply cannot happen
line 152:
list.repaint(rect)

but list was not null before.

Probably caused by webex (remote desktop)
Comment 2 Stanislav Aubrecht 2009-11-06 10:42:25 UTC 
well, if a component was removed from swing hierarchy outside AWT thread, then this exception could happen (i think)
Comment 3 Jan Becicka 2009-11-10 03:18:36 UTC 
but component was not removed at all as far as I remember. Tomas just clicked N/A link in "all issues" node.
Comment 4 Jan Becicka 2010-02-17 01:05:55 UTC 
caused by webex
