OutOfMemoryError while opening .OSM file

[anonymous]

Hi,
JOSM asked me to create an error report after something crashed. I've been loading a file with some OSM data while it crashed. Said file contained the insides of a polygon surrounding my local area. The data has been extracted by osmosis out of the following file:
​http://download.geofabrik.de/osm/europe/germany/nordrhein-westfalen.osm.bz2
I assume the area has simply been too large, and I assume that this bug has been reported before, but I'm new with OSM and therefore I can be too lazy to find out how this bug tracker works. I don't know if this matters, but I'm using debian/stable.
I've attached the osmosis file with the polygon data so that you can reproduce the error, if you are interested.

Try to run JOSM with more memory, i.e. java -Xmx256m -jar josm-latest.jar

Probably my question is stupid, but anyway, how can I run JOSM with more memory? I run it clicking on its icon, and there isn´t any place (with .jar or .jnlp) to choose the memory or type that (Xmx)
