5028	JOSM will not start due to java exception on windows 7	Dane Springmeyer	team	"What steps will reproduce the problem?
This will be difficult to reproduce, but here is what I think happened:

 1. Load custom presents (in the case we are working in Haiti training mappers using the Humanitarian Data model presets
 2. Load them a second time (accidentally in our case)
 3. Nothing odd happened while JOSM was running (that I recall), but upon startup later in day JOSM would not start.

What is the expected result?

JOSM starting.

What happens instead?

JOSM does not start, only displaying splash screen then throwing exception.

In addition, trying to shut down windows fails and says JOSM is still running. JOSM is not registered in the windows task manager, so it cannot be forced to stop. Therefore the only way to try to stop JOSM (for a normal windows user) is to force shut down the machine.

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

Currently trying to uninstall JOSM (can't currently because JOSM is again still running in background). So after filing this ticket I will force the machine to shut down, re-start then try to uninstall JOSM, to hopefully clear out the custom presets that are causing this failure. I cannot locate the preferences file to delete it, but I would assume this would also fix the problem.
