JpaMetamodelUtils can not find the version attribute if it is in a @MappedSuperclass about blaze-persistence

[kuhnroyal]

I managed to boil it down to a simple reproduction: https://github.com/kuhnroyal/blaze-problems/tree/main
The problem seems to happen as soon as more than one subclass entity of the @MappedSuperclass with the version field exists. This might actually be a problem with the Hibernate meta model.

Thanks for the report. Do you think you could quickly create a reproducer based on our quickstarts?

This quickstart should give you a project template for that purpose:

mvn archetype:generate "-DarchetypeGroupId=com.blazebit" "-DarchetypeArtifactId=blaze-persistence-archetype-entity-view-sample-jakarta" "-DarchetypeVersion=1.6.9"

Thanks so much. Since you dug into this and think this could be a Hibernate ORM issue, would you mind trying to see if you can reproduce an error with just Hibernate ORM?

I added a plain HibernateTest

This is great, thanks for your efforts. Would be awesome if you could create a Hibernate Jira issue so you can also track the efforts for that bug. Also, if you create the issue, please share the link here for cross reference.

Thanks for creating the Jira. I'll try to fix it in Hibernate ORM as soon as possible.
