I've uploaded a new version of Chris Rogers' original test case that shows the bug in Hibernate 5.0.0. It's modified to be a gradle project and I've been able to run it against multiple versions of hibernate by changing the version in the dependencies (3.6.10.Final, 4.3.7.Final and 5.0.0.Final). Hopefully this will be enough.

I can also confirm that solution from the patch by Rostyslav Smirnov works for 4.3.7.Final
