JDI test against 'ThreadReference.ownedMonitorsAndFrames' fails because of crash in debuggee VM.

Bug is reproducible on machine vm-amd64-02.sfbay, it is possible to use rdesktop to login on this machine (if you need login/password I can send it in separate email).
To reproduce:
run bash
cd Y:/weekly/mustang/results/1.6.0-rc-b95/ServerVM/64BITWIN03-AMD64/mixed/VM6/nsk.jdi-14-WEEKLYmtg-VM6-ServerVM-mixed-64BITWIN03-AMD64-2006-08-15-22-20-34-0222/ResultDir/ownedMonitorsAndFrames007
sh ownedMonitorsAndFrames007.tlog
(bug reproduces not every time, run script several times)
