RFR: JDK-8201442: objArrayOopDesc::atomic_compare_exchange_oop() must use obj+offset in HeapAccess call

[Roman Kennke]

Please review the following little change.


objArrayOopDesc::atomic_compare_exchange_oop() currently computes and
uses a raw pointer to pass to HeapAccess::oop_atomic_cmpxchg(). It
should use the object+offset variant because it's accessing the heap and
GC might need to resolve the target object (e.g. Shenandoah).
