[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-441) nullable=true is ONLY a hint for schema generation, but Hibernate uses it for validation

nullable=true is ONLY a hint for schema generation, but Hibernate uses it for validation ---------------------------------------------------------------------------------------- Key: EJB-441 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-441 Project: Hibernate Entity Manager Issue Type: Bug Affects Versions: 3.3.2.GA Reporter: Francisco Peredo With the following JPA @Entity (note the @Basic(optional=true), @Column(nullable=false) at the getName method): @Entity public class Customer { private Long id; private String name; @Id @GeneratedValue(strategy=GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Basic(optional=true) @Column(nullable=false) public String getName() { return name; } public void setName(String name) { this.name = name; } } And then the following test @Test public void persistCustomerInTransaction() throws Exception { factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME); EntityManager em = factory.createEntityManager(); em.getTransaction().begin(); Customer customer = new Customer(); em.persist(customer);em.getTransaction().commit(); em.close(); } What exception should be the root cause of this problem? According to the spec @Column(nullable=false) is JUST a schema generation hint, and Hibernate should NOT use it for object level validation, so it should crash with a java.sql.SQLException as the root exception, and not with a org.hibernate.PropertyValueException thrown by org.hibernate.engine.Nullability.checkNullability.
