      Description

      AccessBarrierSupport::resolve_unknown_oop_ref_strength() returns an incorrect oop ref strength for referents in FinalReference objects. It currently returns ON_WEAK_OOP_REF when it should return ON_STRONG_OOP_REF. This is not really an issue for any GC except ZGC when using the ZHeapIterator to walk the heap while resurrection is blocked.
