-----------------------------------------
javadoc warnings are unrelated to this patch. I am not sure why javadoc
warnings unnecessarily flags this as warnings for the patch!

> In ProtobufRpcEngine the client side exceptions are wrapped in
> RpcClientException. The RpcClientException is used to create RemoteException
> which is set as cause in the thrown ServiceException. However
> WritableRpcEngine throws the client encountered exception as is. This
> difference in behavior causes, many tests to fail in the existing unit tests,
> which expect the client invoker() to thrown the exception as is. This jira
> makes the ProtobufRpcEngine behavior consistent with that of
> WritableRpcEngine.
