OpenJDK 7 is a 64bits JVM whereas Apple JDK 6 is a 32/64 bits VM. So larger memory footprint.
I allready pointed this and we should wait OpenJDK 7 for OSX to re-enable a 32/64bits VM mode or at least pointers compression (it's no more the case).
Both showed as 64 bit in Activity Monitor. This may very well be the largest part of it but the JConsole heap graphs looked considerably different between the two applications and the information seemed to indicate different methods for gc. I guess I was wondering if there is anything we should know about this as well?
