Reportedly the maximum on 32 bit systems is 1536M (yes you might
abbreviate it in this way for the command line) and on windows it's
1300M (again: reportedly)

Furthermore you shouldn't give java more than you have in total RAM,
preferably you use a bit less, since heap space is not the only kind of
memory java uses.

on a 1 GB RAM machine I'd suggest in the vicinity of -Xmx512M or -Xmx768M
