Change By: Christoph Watzl ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... )
We are currently trying to upgrade a project from Hibernate 5 to 6, which
When using an {{@Embedded}} value object that has a collection with orphan removal, trying to delete the root entity throws a {{PropertyAccessException}}. The same scenario used to work without issue in Hibernate 5.
I have prepared a [minimal example project to reproduce|].
Model:
{code:java}@Entity
public class Parent {
@Id
private final String id;
@Embedded
private final Child child;
// ... ctors & accessors ...
}
@Embeddable
public class Child {
@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
private final List<Grandchild> grandchildren = new ArrayList<>();
// ... ctors & accessors ...
}
@Entity
public class Grandchild {
@Id
private final String id;
// .. ctors & accessors ...
}{code}
Test case:
{code:java}var parent = new Parent("123", new Child(List.of(new Grandchild("xyz"))));
entityManager.persist(parent);
entityManager.flush();
entityManager.clear();
entityManager.remove(entityManager.getReference(Parent.class, "123"));
entityManager.flush(); // throws PersistenceException{code}
This will throw:

Apparently, for some reason, {{AbstractEntityPersister}} is trying to reflectively access the id property of the Parent entity but applies the getter to the embeddable child value type, which makes no sense.
