long name of image with comma causes exception

[malenki]

Amongst others I have an image descriptively named
dscf_F30-2_011621_Gjirokastra_-_Häuser_alt_und_neu,_dahinter_links_Gjerë-,_dahinter_Kendrevica-Berge,_rechts_Lunxhëria-Berge.jpg

When I run JOSM like this
java -jar ~/bin/josm-archive/josm-4900.jar ./

everything is fine.

But running JOSM like this

java -jar ~/bin/josm-archive/josm-4900.jar dscf*jpg

causes following error:
