When initializing version attribute to a negative value then a TransientObjectException is thrown when loading an entity

I have two entities RootEntity, and ChildEntity that are connected via a bidirectional OneToOne relationship. Both entities have a int version attribute which is initialized to -1 for newly created entities that are not yet persisted.

Persisting newly created entities root1 <-> child1, this is successful. However, when trying to load those entities in a new transaction, then I get an exception with the following stacktrace:

A corresponding reproducer test case is available here:

This reproducer test case can be successfully executed in Hibernate <= 6.6.1. In contrast, the test case fails in Hibernate 6.6.2 and 6.6.3.
