[JIRA] (HHH-16440) Classleak in the BytecodeProviderImpl

by Thorsten Goetzke (JIRA)

Thorsten Goetzke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=6422e66... ) *commented* on HHH-16440 ( https://hibernate.atlassian.net/browse/HHH-16440?atlOrigin=eyJpIjoiNDEzYT... ) Re: Classleak in the BytecodeProviderImpl ( https://hibernate.atlassian.net/browse/HHH-16440?atlOrigin=eyJpIjoiNDEzYT... ) I played around a bit with the bytecode enhancement. It seems to work only with JPA Annotations, however we are stuck with hibernate 3 hibernate-mappings xml… hibernate.transform_hbm_xml.enabled seems to be 90% unimplemented and I am really not hyped about manually migrating hundreds of entities to JPA annotations. But I guess we need to do it at somepoint,,, ( https://hibernate.atlassian.net/browse/HHH-16440#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16440#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!

I assume that join part of query added when using @EntityGraph is also spring data part, right?

[JIRA] (HHH-16885) Hibernate 6.x changes outer to inner join when @EntityGraph and @Id

by Konrad Wajs (JIRA)

Konrad Wajs ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5dea973... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiOGZlMTYzZDUy... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16885?atlOrigin=eyJpIjoiOGZlMT... ) HHH-16885 ( https://hibernate.atlassian.net/browse/HHH-16885?atlOrigin=eyJpIjoiOGZlMT... ) Hibernate 6.x changes outer to inner join when @EntityGraph and @Id ( https://hibernate.atlassian.net/browse/HHH-16885?atlOrigin=eyJpIjoiOGZlMT... ) Issue Type: Bug Affects Versions: 6.2.6 Assignee: Unassigned Components: hibernate-core Created: 03/Jul/2023 12:50 PM Environment: spring boot 3.1.1 Java 17 Postgres and H2 Priority: Critical Reporter: Konrad Wajs ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5dea973... ) I'm using @EntityGraph to eagerly load some attributes. However, something broke after updating from 5.x to 6.x. Suppose we have a human who can have multiple houses: public class Human { @Id @Column(name = "ID" , nullable = false , updatable = false , precision = 20) @GeneratedValue private BigInteger id; @EqualsAndHashCode.Exclude @ToString.Exclude @OneToMany(mappedBy = "human" , cascade = CascadeType.ALL) @OnDelete(action = OnDeleteAction.CASCADE) private Collection<House> houses; } When searching for a human, by ID, EntityGraph can eagerly load some attributes: @EntityGraph(attributePaths = { "houses.address" }) @Query ( "SELECT h FROM Human h WHERE h.id = ?1" ) Human findByIdEagerHouseAddresses( Integer id); This will create SQL with left (outer by default) joins: select h1_0.id, h2_0.human_fk, h2_0.address_fk, a1_0.id from human h1_0 left join house h2_0 on h1_0.id = h2_0.human_fk left join address a1_0 on a1_0.id = h2_0.address_fk where h1_0.id in (?) This is acceptable because I will get the human even if they don't have a house. However, if the address field in the house has the @Id annotation, the outer join will change to "inner": @Entity public class House { @Id @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "human_fk" , nullable = false , updatable = false ) private Human human; @Id // THIS ANNOTATION WAS ADDED @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "address_fk" , nullable = false , updatable = false ) private Address address; } select h1_0.id, h2_0.human_fk, h2_0.address_fk, a1_0.id from human h1_0 left join house h2_0 on h1_0.id = h2_0.human_fk join address a1_0 on a1_0.id = h2_0.address_fk where h1_0.id in (?) If a human does not have a house, the query returns nothing due to the inner join, which seems like a bug.

[JIRA] (HHH-16440) Classleak in the BytecodeProviderImpl

by Sanne Grinovero (JIRA)

Sanne Grinovero ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16440 ( https://hibernate.atlassian.net/browse/HHH-16440?atlOrigin=eyJpIjoiNmVmNT... ) Re: Classleak in the BytecodeProviderImpl ( https://hibernate.atlassian.net/browse/HHH-16440?atlOrigin=eyJpIjoiNmVmNT... ) Thanks for the context. Indeed, I’d love to improve on this but in terms of priorities over other issues I’m afraid this isn’t high on the list. I could also suggest to you: use the build-time enhancement plugins? We have plugins for both Maven and Gradle for people to perform the Bytebuddy enhancement phase at build time; Hibernate ORM can also do it “at runtime” but it’s indeed intended for application servers and containers. You’re right this could be documented better. Build-time enhancement also has the benefit of failing during the build in case of problems, rather than down the line, and saves resources at bootstrap. There’s a special cathegory of proxies which will require runtime enhancement (the “enhanced proxy”), so performing build-time enhancement won’t 100% protect you from leaks, but enhanced proxies are only used on certain kinds of mappings, so I expect such an approach, while not perfect, to still significantly reduce the amount of classes being defined during your integration tests.
