java.util.concurrent.atomic.AtomicBoolean.weakCompareAndSet()
Atomically sets the value to the given updated value if the current value {@code ==} the expected value.
May fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to {@code compareAndSet}. @param expect the expected value @param update the new value @return {@code true} if successful
