Issue Type: Bug Affects Versions: 5.4.11 Assignee: Unassigned Components: hibernate-core Created: 12/Feb/2020 01:51 AM Environment: OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~18.04-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)
Ubuntu 18.04 LTS
PostgreSQL 10+190ubuntu0.1 Priority: Minor Reporter: lukas.schmidt ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5e42a782bbb5110c9a66931e )

We get this warning when executing the reported query:

HHH000487: The query: [update PvDb r set r.externalId = :externalId where r.id = :id] attempts to update an immutable entity: [PV_DB]

We execute the following code (simplified):

           String hql = "update PvDb r set r.externalId = :externalId where r.id = :id" ;
           Session session = sessionFactory.openSession();
           Query query = session.createQuery(hql);
           query.setParameter( "externalId" , externalId);
           query.setParameter( "id" , id);
           int updateCount = query.executeUpdate();

These two classes are mapped to the table PV_DB:

@Table(name = "PV_DB" )
@Entity
public class PvDb extends PvDbCommon

@Table(name = "PV_DB" )
@Entity
@Immutable
public class PvDbTO extends PvDbCommon

@MappedSuperclass
public class PvDbCommon

In the executed query, an object instanceof PvDb is referenced, but no PvDbTO. Nevertheless the warning is shown. The update is executed successfully.

Expected result: The update is executed successfully, but no warning is shown.
