@shipilev you said that the test fails with some other GCs (Parallel, Shenandoah, ...). Who is responsible to select the GC algorithm? What I'm asking is whether one should explicitly enumerate several @runs of the test with explicit selection of different GCs (which ones?) or is this a matter of some external test infrastructure that runs all the tests in the suite and pre-selects different GCs for them?
