[15] RFR(S): 8235332: TestInstanceCloneAsLoadsStores.java fails with -XX:+StressGCM

Hi Christian,

If there's no GC barrier then:

Node* control_proj_ac = bs->step_over_gc_barrier(proj_in->in(0));

control_proj_ac is not a projection, it's proj_in->in(0) so the test
below can never succeed?

Roland.
