Great tool. Maybe my dataset is getting too large?

Yes, java has run out of memory. You can increase the limit using the -Xmx option, you'd have to call josm like this then:

$ java -Xmx512M -jar josm.jar

If you're using a 64-bit VM, you might want to consider to use a 32-bit VM instead, that should decrease memory usage further.
