No lifecycle events for @Embeddable entities in collections

Hibernate ORM
1

Hi Everyone,
I have posted a question in Stack Overflow


but so far no luck.

Here is a copy-paste of the description.

I am trying to get lifecycle related callbacks on Embeddable beans using Hibernate 5.4.10.Final. I have been able to locate a bug seemingly related to this issue
https://hibernate.atlassian.net/browse/HHH-12326
but it states the problem has been fixed in earlier Hibernate versions and I am definitely still seeing the issue it in collections of Embeddable.

I took the example from
https://javabydeveloper.com/mapping-collection-of-embeddablecomposite-types-jpa-with-hibernate/
and modified it slightly to illustrate the problem

I put a sample app here
https://github.com/pzieminski/collection-of-embeddables1

create table user
(
 id           int primary key,
 user_name    text,
 password     text,
 created_time datetime,
 updated_time datetime,
 user_type    text
);

create table contact_address
(
 street_address text,
 state          text,
 city           text,
 zip_code       text,
 user_id        int references user,
 addr_type      text
);

create table contact
(
 contact_ text,
 id       int references user
);

Then I have the beans

@Data
@Entity(name = "user")
public class User {

   @Id
   @Column(name = "id")
   private Integer id;

   @Column(name = "user_name")
   private String userName;

   @Column(name = "password")
   private String password;

   @Embedded
   private Audit audit = new Audit();

   @ElementCollection
   @CollectionTable(name = "contact_address", joinColumns = @JoinColumn(name = "user_id"))
   @AttributeOverride(name = "streetAddress", column = @Column(name = "street_address"))
   private List<ContactAddress> address;

   @ElementCollection
   @CollectionTable(name = "contact", joinColumns = @JoinColumn(name = "id"))
   @Column(name = "contact no")
   private Collection<String> contacts;

   @Enumerated(value = EnumType.STRING)
   @Column(name = "user_type")
   private UserType userType;

   @PrePersist
   public void prePersist() {
       System.out.println("User#prePersist"); // called
   }

}

@Embeddable
public class Audit {

   @Temporal(value = TemporalType.TIMESTAMP)
   @Column(name = "created_time")
   private Date creationTime;

   @Temporal(value = TemporalType.TIMESTAMP)
   @Column(name = "updated_time")
   private Date updatedTime;

   @PrePersist
   public void prePersist() {
       System.out.println("Audit#prePersist"); // called
   }
}

@Data
@Embeddable
public class ContactAddress {

   @Column(name = "street")
   private String streetAddress;

   @Column(name = "state")
   private String state;

   @Column(name = "city")
   private String city;

   @Column(name = "zip_code")
   private String areaCode;

   @Column(name = "addr_type")
   private String addressType;

   @PrePersist
   public void prePersist() {
       System.out.println("ContactAddress#prePersist"); // NOT called
   }
}

And in the interaction below the @PrePersist on ContactAddress is not called. It is called on Audit though.

txRunner.runInNewTransaction(() -> {
   User user = new User();
   user.setId(1);
   user.setUserName("J Doe");

   ContactAddress address = new ContactAddress();
   address.setCity("Las Vegas");
   address.setState("NV");

   user.setAddress(Collections.singletonList(address));
   em.persist(user);
});

Is this a bug? Expected? Has anyone else run into this?

Thank you!
