I've tracked and hunted down a small but impacting bug for Hibernate OGM.
https://hibernate.onjira.com/browse/HHH-6724
I am not sure about the CR status but if you could squeeze this one in, I would be
grateful. I have committed it in upstream master and all tests pass.
BTW this bug was also present in the (future) metadata source part of the code (in some
form). Inheritance could not have worked before the fix. I'm not sure it works now but
that's one step closer :)
