Thank you for the quick answer.

So if I understand it correctly, this was never supposed to work in Hibernate 6 but until 6.2 it worked (magically ) and now it was fixed so that it’s compliant.

Sadly, the migration guide doesn’t state why it was changed and I also couldn’t find why it was changed when searching after it.
Is this documented somewhere, why it was actually changed? A link to an issue/discussion somewhere would be great 🙂
