Addition: The second and all further starts of JOSM then succeed, until I reboot...

Can you try to delete or rename josm settings folder ...\Application Data\JOSM or .josm on Linux? The bug should be gone.

[juergen.kremp@…]

Bingo!

Thanks for the quick hint. That worked.

I have to admit that since last time I worked with JOSM, some time has passed (> 2 years), so it is likely that some old content in the "preferences" caused the issue. Although classified by the error popup as "this is always a program error...", I think fixing this bug is gold-plating.

Nevertheless this is a bit strange. That the issue reappeared after reboot indicates, that your settings get reversed after reboot, or that we somehow did trigger a java startup bug. I found no clear bug in code and as the issue is solved I don't think it needs further investigations.
