A lot of Eclipse's dependencies are used by Tomcat and JOnAS, and JOnAS's testsuite has issues with running out of address space on 32-bit. That's one instance where 64-bit is useful: I expect there are others. I bet there's people out there who'd get upset if all the Java stuff got rebuilt as 32-bit. Cheers, Gary
