Hibernate ORM 6.1.7.Final released

Posted by    |      

Today, we published a new maintenance release of Hibernate ORM 6.1: 6.1.7.Final.

What’s new

This release includes some important bug fixes.

Bugfixes

OneToMany and @Where annotation

We have fixed a bug causing an EntityNotFoundException to be thrown when EntityManager#refresh() is called for a parent entity having a child annotated with @Where (see HHH-15902)

Embeddables

We have fixed few issues related to embeddables:

  • a PropertyAccessException was thrown when deleting an entity having an embeddable with a collection attribute (see HHH-16007)

  • an ArrayIndexOutOfBoundsException was thrown when loading an entity having an Embeddable with more attributes than the parent that was causing (see HHH-15778)

  • an IllegalArgumentException was thrown when deleting an entity having an embeddable with a collection attribute annotated with orphanRemoval=true (see HHH-15864)

  • a NullPointException was thrown when the model contains a nested embeddable with a non-optional association (see HHH-15794)

  • a ClassCastException was thrown when a not nullable OneToMany association references an entity with an embedded id (see HHH-15866 see HHH-15865)

  • an IllegalArgumentException was thrown when retrieving by identifier entities extending a MappedSuperclass class with an embeddable id (see HHH-16070)

  • an HibernateException was thrown when querying an entity having an embeddable with a collection attribute with cascade delete orphan (see HHH-16117)

Bytecode enhancement and dirty checking

We have fixed a bug causing the execution of unnecessary SQL update statements when setting a property to its current value (see HHH-16049)

Polymorphic Queries

We have fixed a bug causing an HibernateException when a polymorphic query contains a join (see HHH-15944)

Batching

We have fixed a couple of bugs affecting batch fetching:

  • when refreshing an entity annotated with @BatchSize its lazy associations may be swapped with a wrong instance (see HHH-15851)

  • collection batch fetching generated more queries than needed when retrieving empty collections (see HHH-16043)
