    Alright, I understand that now :-).

> Now every time call connect method in AkkaRpcService class using same address 
> and same rpc gateway class, the return gateway object is totally different 
> with each other which equals and hashcode are not same. 
> Maybe it’s reasonable to have the same result (equals return true, and 
> hashcode is same) when using the same address and same Gateway class.
