21103	JOSM crashing on close, 'java.lang.IlleagleStateException' due to dialog issue	rickmastfan67	team	"Just happened to notice this when closing JOSM in my CL window.  Sadly, it's very quick in closing, so I don't have a text log of the issue, just an Print Screen that I was able to snag since the window disappears on it's own very quickly.

Tested this with my normal and a fresh profile and was able to duplicate it in both.

Steps to reproduce:
1) Once JOSM is started, download a small area of data (doesn't matter how big).
2) Close JOSM.

What happens:
JOSM crashes in the CL with 3 issues (see attached image), the worst being an 'java.lang.IlleagleStateException' issue (manually typed below).

{{{
SEVERE: java.lang.IlleagleStateException: Dialog not created yet. Invoke createInstance<> first
}}}

Doesn't trigger if no data is downloaded.
