Cannot use @MappedSuperclass and @Inheritance together

Hibernate ORM
1

I remember being able to use @MappedSuperclass and @Inheritance together. Did something change in a specific version of Hibernate? Maybe this is illegal per JPA standards?

Consider the following slimmed-down classes:

@MappedSuperclass
public class ModelBase<ID extends Serializable> implements Serializable {
  @Id
  @GeneratedValue
  protected Long id;
}

@Table(name = "account", schema = "finance", uniqueConstraints = @UniqueConstraint(columnNames = "name"))
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public class Account extends ModelBase<Short> implements Serializable {
  @Column(name = "name", nullable = false, insertable = true, updatable = true)
  protected String name;
}

@Table(name = "account_banking", schema = "finance", uniqueConstraints = @UniqueConstraint(columnNames = {"account_number", "routing_number"}))
@Entity
@PrimaryKeyJoinColumn(name = "id")
public class AccountBanking extends Account {
  @Column(name = "account_number", nullable = false, insertable = true, updatable = true)
  private String accountNumber;

  @Column(name = "routing_number", nullable = false, insertable = true, updatable = true)
  private String routingNumber;
}

The following is thrown:

This should work. Maybe it’s an issue related to identifier quoting. Did you enable hibernate.globally_quoted_identifiers? If so, and if it works without that, you should create an issue in the issue tracker.

Oddly enough, removing the @Table schema parameters, the problem goes away.
