The documentation only supplies an example for TCP/IP

Can you try to create your Hazelcast instance like this:

Config cfg = new Config();                  
HazelcastInstance hz = Hazelcast.newHazelcastInstance(cfg);

The managementcenter stuff and the creation of the executors are not relevant (I added that code in the testapp, so I'm 100% sure about that).

Then you should have exactly the same network configuration as the TestApp.
