JOSM 11223 crashed while initializing. The first screen never appeared; the unexpected exception window appeared instead.

[jpn@…]

What steps will reproduce the problem?

1. This has not happened to me previously with version 11223 of JOSM. I quit JOSM, then reopened it by double clicking the josm-tested-11223 icon, as usual, and JOSM opened normally.

What is the expected result?

The expected result is to see the normal initial JOSM window.

What happens instead?

I was shown the unexpected exception report window. I decided to report the incident.

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