I am just reusing the same test case for [https://hibernate.atlassian.net/browse/HHH-16435|https://hibernate.atlassian.net/browse/HHH-16435|smart-link]
If I add {{configuration.setProperty(AvailableSettings.DEFAULT_SCHEMA, "PUBLIC"); }}we always get a NPE
{noformat}@Entity
@Table(name = "ENTITY_A")
@DiscriminatorColumn(name = "DISC_COL", discriminatorType = DiscriminatorType.INTEGER)
@FilterDef(name = "DUMMY_FILTER", defaultCondition = "(ID IS NOT NULL)")
@Filter(name = "DUMMY_FILTER")
public abstract class AbstractEntityA {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
Integer id;
}{noformat}
{noformat}@Entity
@DiscriminatorValue("1")
public class EntityAChildOne extends AbstractEntityA {}{noformat}
{noformat}@Entity
@DiscriminatorValue("2")
public class EntityAChildTwo extends AbstractEntityA {}{noformat}
{noformat} @Override
protected void configure(Configuration configuration) {
super.configure(configuration);
configuration.setProperty(AvailableSettings.SHOW_SQL, Boolean.TRUE.toString());
configuration.setProperty(AvailableSettings.FORMAT_SQL, Boolean.TRUE.toString());
configuration.setProperty(AvailableSettings.DEFAULT_SCHEMA, "PUBLIC");
}
@Test
public void hhhXXXXTest() throws Exception {

s.persist(entityAChildTwo);
tx.commit();
}
try (Session s = openSession()) {

If I need to use Filters and a default schema, I see not no workaround for this issue.
please find the test case attached and also available at [https://github.com/ratoaq2/HHH-16661|https://github.com/ratoaq2/HHH-16661|smart-link] |
