Comment 2 Stanislav Aubrecht 2013-01-23 16:07:17 UTC 
It's very likely a problem in Plugin Manager UI caused by this JDK bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6429812

All tables in Plugin Manager window use custom table header renders to paint sort icons when necessary. I suggest using RowSorter support introduced in JDK 1.6. It might remove some code that must be maintained now.

We are going to try some workaround of JDK bug -http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6429812. The frequency of NPE has been increased after changeset http://hg.netbeans.org/main-silver/rev/c6c99ec43804

The changeset was rolled back. We can decrease the priority back to P3.
