Your stacktrace indicates that the correlation ID of the reply message
does not match the correlation ID expected by the client.
Off the top of my head, this could happen because of a bug in the RPC
server program, or because there are stale reply messages in the reply
queue.
Do the bundled HelloClient and HelloServer examples work?

Yes, there are: See classes HelloClient and HelloServer, which use
RpcClient and RpcServer, and classes HelloJsonClient and HelloJsonServer
which use JsonRpcClient and JsonRpcServer.

Tony
