EVALUATION As this failure seems to be caused by a marking failure, it's very likely it's been fixed by one of three marking bugs we recently identified and fixed: 6940310: G1: MT-unsafe calls to CM::region_stack_push() / CM::region_stack_pop() 6935821: G1: threads created during marking do not activate their SATB queues 6909756: G1: guarantee(G1CollectedHeap::heap()->mark_in_progress(),"Precondition.") I'm closing this as a dup.
