EntitManager#find with IdClass with OffsetDateTime field returns null when Batch is enabled

Description

I have an entity with a composite primary key like this:

@IdClass(MyEntityKey.class)
public class MyEntity {

    @Id
    private Long id;
    @Id
    private OffsetDateTime bookDate;
    private String data;
}

and the ID-Class

public class MyEntityKey implements Serializable {

    private Long id;
    private OffsetDateTime bookDate;
}

After upgrading from hibernate-core from 6.2.1 to 6.2.4 (actually upgrade from Quarkus 3.0.3 to 3.1.1) the em.find() no longer works, but returns `null:

em.find(MyEntity.class, new MyEntityKey(ID, BOOK_DATE)); //returns null

but the same as a query works:

em
    .createQuery("SELECT x FROM MyEntity x WHERE x.id = :id AND x.bookDate = :bookDate", MyEntity.class)
    .setParameter("id", ID)
    .setParameter("bookDate", BOOK_DATE)
    .getResultList();
//returns the value

I was not able to reproduce this with a JPAUnitTestCase, see discourse.
