JIT compilation thread enters a dead loop, stealing all CPU.
If -Xbacth is specified, it does the same thing, and also blocks
normal VM execution.

The problem happens with our product, CDS, and is reproducible in our
environent. Please contact submitter, Pawel Veselov <###@###.###>
for more information.

Unfortunately, our hard requirements are to support WebLogic server SP4,
and it can only run on 1.3.

I was able to extract the stack trace for the thread in question.
