Hibernate Envers : Embedded extended MappedSuperClass raise exception on startup

I'm currently trying to use Hibernate Envers on my project, but I got the following exception. I think it's because of MedicalSummaryId which contains no data and extends a mapped superclass, but I don't see how fix it.

I'm using Hibernate 4.3.8.Final.

Exception :

Thanks for your help.

Solution

  • The problem seems to come from the composite key so, I found a non satisfying workaround, instead of using the composite key, if I use a simple key it's working.
