Previously the tests only returned a tuple of hostname and port iterator. There are two problems with the current approach: 1. We are not shutting down the actor systems 1. The port `22551` might be occupied already. In that case creating the actor system should fail. We can extract the respective logic out of `createRpcService` and test that. Can I take over, or do you want to continue working on this? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
