FontsManager prevents JOSM to start when local disk is full

[anonymous]

What steps will reproduce the problem?

What is the expected result?

JOSM starts

What happens instead?

Error, maybe it was some kind of canceling an upload to OSM before closing JOSM the time before the error occurred with starting JOSM

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

If I translate "uf dem Gerät ist kein Speicherplatz mehr verfügbar" correctly, I get "There is no more memory available on the device".

So likely your disk is full. Please check and close the ticket if that's the case (not a JOSM issue).

In 14382/josm:

see #16908 - make sure FontsManager does not prevent JOSM to start

This specific startup issue is fixed, but you will likely get a ton of other problems if your hard disk is full.
