Argh it's is a Heisenbug!

I'll keep running the test over & over to see if I can get it to happen.

And I'll at least commit that change so when it does happen again we get more detail.

I removed the patch and the test still refused to fail.

I'm not sure what happened - AFAIK I didn't change anything. I ran the test about five times previously and it always failed :(.

Maybe it's Microsoft's gentle way of telling me it's time to move to Vista. :)

Unfortunately the test doesn't give us the traceback on
failure (just
the message "null").  Can you apply this, get the test to fail, and
post back the traceback?

I'm running on Windows XP, with Sun Java 1.4.2_16.

Is anybody else seeing this?
