Comment 2 Stanislav Aubrecht 2012-11-06 15:48:49 UTC 
This doesn't seem to be a JDK issue. List render simply returns a null component for some reason...
Please provide steps to reproduce and reopen, thanks.

Comment 9 Stanislav Aubrecht 2013-06-27 12:41:41 UTC 
I found two instances of null ListCellRenderer - one in Quicksearch dropdown list and one in bugtracking. Fixed in core-main 24de261a3b5c

But there might be other bad renderer implementations so please reopen if still reproducible (and provide steps to reproduce).
