The EntityManager.lock() seems to use the wrong column name when it is passed a sub-type entity froma joined inheritance strategy.

ie, I would expect to see:
update SUPER set ROW_VERSION_SEQ=? where SUPER_ID=? and ROW_VERSION_SEQ=?

but instead I see:

update SUPER set ROW_VERSION_SEQ=? where SUB_ID=? and ROW_VERSION_SEQ=?


which throws a org.hibernate.exception.SQLGrammarException: could not retrieve version:
because column SUB_ID does not exist on table SUPER.






Hibernate core 3.3.1, Anotations 3.3.1, EntityMnager 3.4


@Entity(name = "Company")
@Table(name="COMPANY")
@PrimaryKeyJoinColumn(name = "COMPANY_ID")

public class Company extends Party {
...


@Entity(name = "Party")
@Table(name = "PARTY")
@Inheritance(strategy = InheritanceType.JOINED)
public class Party extends AbstractVersionedEntity implements EntityWithUUID {


private String key;
@Id
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy="uuid")
@Column(name="PARTY_ID")
public String getKey() {
return key;
}

public void setKey(String key) {
this.key = key;
}



@MappedSuperclass
public abstract class AbstractVersionedEntity extends AbstractEntity implements VersionedEntity {

/** The version. */
private Integer version;

@Version
@Column(name = "ROW_VERSION_SEQ")
public Integer getVersion() {
return version;
}
...





Code:

Company company= entityManager.find(Company.class, "12345");

entityManager.lock(company, LockModeType.WRITE);







The generated SQL:

Hibernate: update PARTY set ROW_VERSION_SEQ=? where COMPANY_ID=? and ROW_VERSION_SEQ=?
