That would be the correct answer :) On a 32 bit system, the cap is somewhere between 1.2 and 2 GB. It seems to vary a bit from platform to platform, and VM to VM, but its definitely a hard limit. Sun's documentation on what that hard limit will be per platform is rather sketchy... but the JVM simply won't start with a -Xmx value higher than the magic limit number for your hardware configuration. Gotta go 64 bit if you want to use higher -Xmx numbers.
