So far this bug has been observed with:

- Client VM
- Server VM
- Server-64 VM

And with the following OSes:

- Win-AMD64
- Solaris AMD64
- Solaris X86
- Linux X86

So far there have been no sightings on Solaris SPARC.
However, the failure mode appears to be intermittent
since the failing tests and affected platforms are
different for each nightly.
