Starting with 2016.2 the Java XEP binding will no longer support the in-memory connection mode. The in-memory mode was deprecated in earlier versions and applications should switch to the TCP/IP connection mode instead.
The TCP/IP connection mode has bridged the gap in performance to a large extent over the past couple of years and enables the Java client to run on a remote machine.
Let me know if you have any questions or concerns.
