Created attachment 3088 [details] NullPointerException
> select JPanel in Component Palette This means that you right-clicked JPanel in palette and chose Copy? I cannot reproduce the problem...
Seems that a corrupted component (probably a panel from issue 16805) was copied...
Resolved for 3.3.x or earlier, no new info since then -> closing.
