64bit JVM?

Anyone figure out how to do this? There are no instructions on how to do this but there is a note on the patch logs

The mendelson opensource AS2 will run fine with Java 64 bit VMs. If you have problems with the memory consumption please install a 64 bit java VM (not included), patch the VM with the "jurisdiction policy strength files" (Oracle download) and set the main memory of the JVM to 4 GB.



has anyone been able to do this? I noticed this is now on openjdk and that doesn't even have a jvm folder so you can't just drop the files in.
