I tried to recreate the problem, but everything seems to work fine now and I cannot get the error message again.
same JOSM 2854
same Java
same plugins, but I can't get to the plugins - but I suspect portableApps not JOSM
I change whole ticket to invalid, because i now suspect portableApps. Sorry for the noise.
