I think that means the Windows box does not have SSE4 (or at least not 4.2), which has been the recent problem with String handling. > 2) I thougth 64bit vms would not have a client mode.... You're right, it doesn't, at least on Windows. There is a -XX option to limit or disable SSE usage: -XX:UseSSE=n where n is the highest SSE version to use. Might try setting it to 3 or less and see if anything changes. There's also -XX:-UseSSE42Intrinsics, but that should be off by default already. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
