Unidirectional @OneToOne with @MapsId does not work with lazy loading

Question

I want to map a @OneToOne association using Hibernate 5.3.10 and JPA.

I know that the parent side of a @OneToOne association cannot be load

Answer 1

It looks like this is the HHH-12842. The described approach perfectly works in the hibernate 5.4. But it does not work in the hibernate 5.3 branch.
