Please, have a look at wiki:InstallNotes#MicrosoftWindows for instructions how to make more memory available.

This page includes useful information but it is not much linked to.

Anyway, it would be useful to raise the default memory for windows to 512 MB. Linux is much smarter and does already assign a percentage of total memory. I am not sure if this is also possible with WIndows and I do not know OSX at all.

We cannot tune memory when JOSM is launched via a double-click on JOSM jar.
The shortcut creation with -Xmx1024M is the best way to change this, you can also use the Windows installer.
