I hit something in the menu, and my java perspective went blank but didn't disappear).  Then I tried the context menu on the java tool item and it opened an error dialog.

This bug hasn't had any activity in quite some time. Maybe the problem got
resolved, was a duplicate of something else, or became less pressing for some
reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it.
The information can be, for example, that the problem still occurs, that you
still want the feature, that more information is needed, or that the bug is
(for whatever reason) no longer relevant.

If the bug is still relevant, please remove the stalebug whiteboard tag.
