Konrad, There is a similar case when using AbstractActorSubscriber.
I have defined an actor by deriving from AbstractActorSubscriber. This actor also use WSClient to upload some data to the remote server. I guess I should not let this actor asynchronously execute its task, that might give incorrect back-pressure information to the publisher, so I still use CompletableFuture.get to block the actor's thread. I think I should not stash messages in this case, that also give incorrect information to the publisher. right? Is there any way to not block actor's thread in this case?
