I find it somewhat disturbing that a generic test has to know about the 
limitations between GCs and Graal!

I would have been more inclined to just exclude this test when running 
with Graal, even if that theoretically reduced the test coverage in a 
ting way.

If/When Graal supports these other GCs who will remember to re-enable 
these test cases?

Thanks,
David
