FetchNotFoundException after Upgrade to 6.6.X

Hi @J.Thiele, at first glance I don’t see anything wrong with what you’re trying to achieve here. If this used to work with the latest Hibernate 6.5 version, it might be a bug introduced in version 6.6. If the bug persists with the latest stable release, please open a new ticket in our issue tracker and attach that reproducer test case, thanks.
