"an unexpected exception occurred"

[anonymous]

What steps will reproduce the problem? ¶

I am not sure how to reproduce this. I was editing a relationship, went away to look at information in Firefox, and clicked back into JOSM. This is the first time I witness it.

The application did not crash.

What is the expected result? ¶

What happens instead? ¶

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