Looking at the original report, my guess would be that the test script
is memory hungry.

        at java.lang.Thread.start0(Native Method) [na:1.6.0_37]
        at java.lang.Thread.start(Thread.java:640) [na:1.6.0_37]

It appears to be starting a thread. Quite why that needs to allocate
512M, I don't know. But I'd start by reviewing the script.
