Matt Shaw, I'm not able to run your test as is, due to "Failure to find org.opengeo:geodb:jar:0.8 ".

There is another bugfix that was just resolve related to HHH-11714 Closed , HHH-11996 Resolved . Could you try running your test using Hibernate ORM 5.2.12-SNAPSHOT and let us know if it fixes your issue?
