    Java API for #resolveOne

    Resolve the ActorRef matching this selection. The result is returned as a CompletionStage that is completed with the ActorRef if such an actor exists. It is completed with failure ActorNotFound if no such actor exists or the identification didn't complete within the supplied timeout.

    Resolve the ActorRef matching this selection. The result is returned as a Future that is completed with the ActorRef if such an actor exists. It is completed with failure ActorNotFound if no such actor exists or the identification didn't complete within the supplied timeout.

    Under the hood it talks to the actor to verify its existence and acquire its ActorRef.
