Null pointer exception when app resized by remote desktop

[emilyw]

Had josm open (but wasn't using it) on a machine with a v. large monitor. Remote desktopped into this machine from another machine with a much smaller monitor, causing much window resizing. This apparently caused the following excitement (although I didn't find the error dialog until later so I can't be sure):

The error recurs whenever I dismiss the dialog, so I have to kill the app.

reason for re-opening this ticket:

• similar error reported in #1651 (closed, as I consider this a duplicate)
• exact matching error in #1761 (was closed because of to few background information, I seconded but consider the ticket a duplicate instead

best guess, but maybe new, important conclusion is: it seems to be all about display and or interaction with window systems

I think this relates to a ​in java.

Ok, Java bugs aren't our task.
