Review comment:
If only simple `get()` and `set()` methods are used in `AtomicBoolean`,
it is basically the same as using `volatile boolean` unless methods like
`compareAndSet` and `getAndSet` are required.
https://github.com/AdoptOpenJDK/openjdk-jdk8u/blob/master/jdk/src/share/classes/java/util/concurrent/atomic/AtomicBoolean.java#L85-L87
(although the implementation uses `volatile int`)
But anyway, using `AtomicBoolean` is easier to understand.
