Check test for HHH-18147

[DavideD]

HHH-18147 introduces a lazy initialization that causes regressions in Hibernate Reactive when upgrading to Hibernate ORM.

For the time being, I've sent a couple of PR for ORM that allow us to skip this change. See HHH-18431 and HHH-18381.

I need to have better look at the ORM original issue and possibly port the test they've added if it makes sense.
