HHH-19017: Address ClassCastException for PersistentAttributeInterceptable

[jimsimon-wk]

A ClassCastException is thrown when trying to resolve instances without bytecode enhancement enabled under these preconditions:

• @OnetoOne property on a model
• @joincolumn to a unique key (other than @id)
• @entitygraph being applied with attributes that are not the one-to-one

Related Change in Hibernate 6.6

• HHH-18489 Lazy, unowned one-to-one associations get loaded eagerly in queries - even with bytecode enhancement #8812

• HHH-19017: Reproduce Class Cast Exception for PersistentAttributeInterceptable #9560

Thanks @jimsimon-wk! Just left a few minor comments, but other than that your change looks good to me.

Thanks for the helpful review @mbladel! I thought I had imported the codestyles to IntelliJ, but I must have forgotten to apply formatting. This moved things around a little in the unit test too

It seems your last commit has a typo i.e. you used HHH-19107 instead of HHH-19017 in the commit message. After fixing that, the PR can IMO be merged.

TIL about reword when rebasing... I think we should be good to go now. Thanks for catching @beikov

[jimsimon-wk]

@beikov CI failed on codestyles, so I had to push more updates. Are you able to start the workflow again? Is there a timeline yet on when we can expect this to merge and get released?

[mbellade]

@jimsimon-wk could you please squash all commits to a single one (or one for the test and another for the fix)? After that we can go ahead and merge.

@mbladel No problem. The branch should now be one commit after my last push

@beikov @mbladel I’m facing the same issue after updating to the newest Spring Boot 3.4.4 version, which pulls in Hibernate 6.6.11.Final
