Crash after connecting an external monitor

[botticchio@…]

What steps will reproduce the problem?

1. Open JOSM on a laptop, without external monitors connected
2. Connect an external monitor (please note that in my case the main desktop was the external monitor)
3. Click the maximize window button

What is the expected result?

JOSM window is maximized and operational

What happens instead?

JOSM crashes and triggers the crash reporter. In addition, the crash reporter is opened in the laptop monitor (i.e. the secondary), not on the external (main).

After closing the crash report window, JOSM is still operational, apparently without issues.

Please provide any additional information below. Attach a screenshot if possible.
