BehaviorSubject.scan not picking up initial value

[mbrandonw]

I would expect this:

final Observable<Void> ob = BehaviorSubject.create();
ob.scan(0, (accum, x) -> 123)
  .subscribe(x -> {
    Timber.d("Hit!");
  });

to emit a value (and indeed it does in the equivalent RxJS code).

Is this a bug?

This is odd. The initial value is emitted just before the first accumulated value or a completion event.
