Review Comment:
For objects like this where there could be many in existence at the same
time or in some use cases can be created and destroyed quickly I tend to prefer
an AtomicIntegerFieldUpdater and a volatile int so that each StompConnection
object doesn't need to create a new AtomicBoolean. Just a minor thing and up
to you if you see value in it for this case.
```
private static final AtomicIntegerFieldUpdater<StompConnection>
DESTROYED_UPDATER =
AtomicIntegerFieldUpdater.newUpdater(StompConnection.class,
"destroyed");
private volatile int destroyed;
...
if (DESTROYED_UPDATER.compareAndSet(this, 0, 1)) {
....
}
```
