Internal notes: the standard cycle of start(true) and shutdown does not introduce a memory leak on the Java side: the PythonClient, JavaServer, and ClientServerConnection are correctly garbage collected once the ClientServer is shut down.

Still need to test what happens when the JavaServer is on a long-living thread.
