We have upgraded the hibernate-core version from 5.4.21.Final to 6.4.0.Final. and we are facing the same exception UnsupportedOperationException(“Re-work support for semi-resolve”);

Further, we have observed this in the case of one-to-many join (@JoinColumn Annotation) along with the findAll method for that entity and where the **referencedColumnName** is null.

Also, in hibernate-core version before 6.x ([hibernate-orm/hibernate-core/src/main/java/org/hibernate/type/CollectionType.java at main · hibernate/hibernate-orm · GitHub](https://github.com/hibernate/hibernate-orm/blob/main/hibernate-core/src/main/java/org/hibernate/type/CollectionType.java) ) method getKeyOfOwner (line 438)

`if ( !returnedClass.isInstance( id ) ) { id = keyType.semiResolve( entityEntry.getLoadedValue( foreignKeyPropertyName ), session, owner ); }`

now in versions 6.x (including 6.4.0.Final) the same method is changed to the below snippet.

` if (!keyType.getReturnedClass().isInstance(id)) { throw new UnsupportedOperationException("Re-work support for semi-resolve"); } else { return id; }`

For us, it is failing in 6.4.0.Final where id is null. The same case was working in version 5.4.21.Final

Could you please help?

The stacktrace looks like this

This happens to me when Lombok is used for collections e.g.

```auto
@OneToMany
@JoinColumn(name = "BATCH_JOB_EXECUTION_ID", referencedColumnName = "BATCH_JOB_EXECUTION_ID")
@Builder.Default // Causes re-work support for semi-resolve
private Set<JobExecutionParameter> parameters = new HashSet<>();

```

I think that this issue was reported as [[HHH-17184] - Hibernate JIRA](https://hibernate.atlassian.net/browse/HHH-17184), so you can watch that to get updates about the current state.  
If you care about this, please consider contributing a test case or also a fix.
