I have two entity classes which are byte-code instrumented: Person and Address. A person has an optional one-to-one address. The PK of the Address class is the FK of Person.
Code:
@Entity
public class Person {
...
@OneToOne(mappedBy = "person", cascade = ALL, orphanRemoval = true)
@LazyToOne(LazyToOneOption.NO_PROXY)
@PrimaryKeyJoinColumn
private Address address;
...
}
@Entity
public class Address {
...
@Id
private Long id;
@MapsId
@OneToOne
private Person person;
...
}
When I attempt to delete a Person record, I get the following error:

If I remove the byte-code instrumentation, the cascaded delete works as expected.
Any ideas about what I might be doing wrong?
Thanks
