Lines 3004 to 3010 in 0c798da

	PacketReference errValue = PacketReference.createReference(null, null, null);
	PacketReference o = destMessages.removeWithValue(id, remoteRef, errValue, r);
	if (o == errValue) { /* intended */
	logger.log(((DEBUG_CLUSTER || getDEBUG()) ? Logger.INFO : Logger.DEBUG),
	"Requeued message found on removing remote reference@" + remoteRef.hashCode() + "=" + remoteRef + "[" + id + "]");
	return ret;
	}

causes messages in cluster to not be ACKed.
