Closed as duplicate of #21740.
You may need to delete the RoadSigns.jar file (for the roadsigns plugin) to work around this bug.

See https://josm.openstreetmap.de/wiki/Help/Preferences#JOSMpreferencedatacachedirectories for data locations. You will need to delete the RoadSigns.jar file in the plugins directory (see https://josm.openstreetmap.de/wiki/Help/Preferences/Plugins#Manualinstallation ).

Problem was in core.
