Hello all,

reading on the "new" memory model and AtomicReferenceArray, it
seems that anything done before a .set() on an AtomicReferenceArray
"happens-before" anything done after a .get() on the same
AtomicReferenceArray.

Two questions:

1. Am I right?
2. If so, does this hold true if the write does not actually change
   the value, in other words, if the write only "refreshes" the
   memory location?

Thank you

	V.B.
