> FTR, I discussed this privately with Tobias. His concern is that the test would not be run if not passed `-XX:+UseParallelGC`. That doesn't seem to be an issue though as the test runs as expected when passed no option or `-XX:+UseParallelGC` and doesn't run with a command line option that enables some other gc.
Which means it will run with default GC: G1.
