Exception occurs with the use of entitygraph loadgraph in case InheritanceType.JOINED is used and the parent class is queried (testcase attached).
when using loadgraph the following exception occurs:

{noformat}
if the subgraph to fetch the embedded entity is removed then the first error occurs both with loadgraph and fetchgraph.
Seems that there is an error when using embedded type with entitygraph as well as when using inheritance with entitygraph.

[JIRA] (HHH-16007) PropertyAccessException when deleting entities with Embeddables with child collections

Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNDRiNTk3NGNi... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16007?atlOrigin=eyJpIjoiNDRiNT... ) HHH-16007 ( https://hibernate.atlassian.net/browse/HHH-16007?atlOrigin=eyJpIjoiNDRiNT... ) PropertyAccessException when deleting entities with Embeddables with child collections ( https://hibernate.atlassian.net/browse/HHH-16007?atlOrigin=eyJpIjoiNDRiNT... )
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 an [ minimal example project to reproduce test | https://github.com/cwatzl/hhh-16007 ] project to demonstrate the issue.
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}

Of particular interest is this message:
{noformat}Can not set final java.lang.String field org.hibernate.bugs.model.Parent.id to org.hibernate.bugs.model.Child{noformat}
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.
