What steps will reproduce the problem?

I don't know if it's reproducible. I was editing a map based on pretty large GPX.

What is the expected result?

JOSM should quit without an exception.

What happens instead?

Exception received.

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