Intermittent failure from my nightly analysis report:

New nsk.quick-jdi failures (from 2008.12.12)
    nsk/jdi/stress/serial/forceEarlyReturn002
        This test failed due to "java.io.StreamCorruptedException:
        invalid type code: 00" on Linux AMD64 Server VM (machine
        pupkin). There is an entry for a different failure mode for
        forceEarlyReturn002 below.

        Last failure on 2009.02.11 with Solaris X86 Server VM -Xmixed (machine sunfire005)
        Previous failure on 2009.02.04 with Solaris X86 Server VM -Xmixed (machine sfv20-02)
