Review comment:
Maybe wrap in `AkkaRpcException("Failed to serialize the result for RPC call
%s.", e)`

>
> The {{AkkaRpcActor}} should check whether an RPC response which is sent to a
> remote sender does not exceed the maximum framesize of the underlying
> {{ActorSystem}}. If this is the case we should fail fast instead. We can
> achieve this by serializing the response and sending the serialized byte
> array.
