Not sure if it helps, but if we can piggyback on the volatile write to phase, then we could structure it like so:


                    if (unlock != 1) {
                        U.putReference(this, ARRAY, newArray);
                        phase = unlock;
                    } else {
                        U.putReferenceVolatile(this, ARRAY, newArray);
                    }
