Steve, no not yet. In your test you use a persistence-unit-defaults general entity listener. I've tried to get a listener running per entity. So I thought I give the persistence-unit-defaults version a try in our application. No luck, listener doesn't get called.
I compared your and my configs. Both are looking good. Now I want to play around with your test, however had some issues getting the hibernate-orm project to build on my box. Finally got the build running (w/o tests) but importing to idea doesn't: "Could not create plugin of type 'MatrixMetaPlugin'". Haven't looked at this yet, but will do today. Some gradle issue for sure.

Thx again for looking into this. I'll keep you updated.
