2.x: Disposal of ObservableCombineLatest's observers?

[jbarr21]

When a ObservableCombineLatest is disposed, is there any particular reason why it does not dispose all of it's observers? i'm seeing getAndIncrement() be non-zero and that observer is not receiving any more events, so a memory leak is caused

If there is no ongoing onNext, that should dispose the sources. Does your downstream block for any reason on onNext?

Flowable is implemented with an eager cancellation so I consider this to be a bug. I'll post a fix shortly.

Closing via #5114.

@akarnokd, thanks for the quick turnaround! would this also apply to ObservableZip, as well? here is FlowableZip's cancel()

[akarnokd]

Indeed. Would you like to submit a PR?

will do
