> Affects Versions: 10.5.1.2
> Environment: java version "1.5.0"

> We made a change to enable the "Virtual Machine Interface " between the VM
> server and the SUSE Linux client, to correct a time calculation issue in this
> environment. Since then we have been seeing intermittent hangs, once in the
> build during splitmessages and several times in the tests. The hang always
> seems to be in some native code invoked from an internal java class.
> This is lkely a VMWare bug, rather than Derby or JVM bug. Once that is
> verified I will close this invald, but thought I would file it in case users
> encounter the issue.
> I will post a few sample javacore files. Here is one sample trace:
