> 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}}.
