Just curious - the test runs with a max of 10 GCs. You reproduced this bug on a slower machine with fastdebug build. If you increase the max number of GCs, I wonder how long the test will take to complete/pass? Around 14 GCs (runtime with -Xcomp approximately 40 seconds on that particular machine). Would increasing the max to 20 fix this bug? I don't have a strong objection to call System.runFinalization. As I don't know what behavior the test wants to cover, adjusting the number of max GC invocations seems a good alternative.

I have no idea either. It's a very old test from Mark. I would be fine with increasing the GC count but for even slower machines (VMs) it might not be enough.
