OK, thanks for clearing that up. Wish Sun was as clear. That does explain why I had issues with 32-bit Windows. (not my 1st OS choice)

The total heap (NewGen + OldGen + PermGen) is allocated in one contiguous chunk of virtual space, which can be a problem when fitting it all in on a 32-bit process. However, the -Xmx is just for NewGen + OldGen; the PermGen size remains independent. This has been true since HotSpot was first available. Prior to HotSpot, instances of java.lang.Class were allocated from the general Java heap, not segregated. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
