> The {{RpcService}} implementation should throw an exception (returned in the
> future) if {{RpcService.connect(address, type)}} cannot connect to the remote
> {{RpcEndpoint}}.
> At the moment the {{AkkaRpcService}} does not check that the
> {{IdentifyActor}} message contains a valid {{ActorRef}} and throws due to
> that a {{NullPointerException}}.
