An update on this, it seems I can only get the exception if I have the second node in the cluster. If I just run the Java code against a single server node it doesnt throw the error. However, it still takes a very long time to connect.
Here is the output from the topology change in the console, it seems a bit odd that its assigning 10 cpus for such a simple hello world operation!
