7041440: G1: assert(obj->is_oop_or_null(true )) failed: Error #
Summary: During an evacuation pause clear the region fields of any concurrent marking task whose local finger points into the collection set as the values in the region fields will become stale. Clearing these fields causes the concurrent mark task to claim a new region when marking restarts after the pause.
