HHH-19017: Reproduce Class Cast Exception for PersistentAttributeInterceptable

[jimsimon-wk]

Reproducer for https://hibernate.atlassian.net/browse/HHH-19017

This is not a fix, just a reproducer for an issue I encountered after upgrading to Hibernate 6.6 (from 6.5). I originally thought that the issue was confined to @OneToOne(FetchType.LAZY) but this test also fails for FetchType.EAGER. I believe the preconditions to reproduce this are

1. @OneToOne property on a model
2. @JoinColumn to a unique key (other than @Id)
3. @EntityGraph being applied

This test should reproduce a ClassCastException that's thrown here.

Hey. No, people reporting issues generally create the Jira ticket, with a link to the reproducer :)

My apologies! I didn't realize I could (and had to) create an account to create a ticket in the project.
