[hibernate-issues] [Hibernate-JIRA] Created: (HHH-4880) EntityManager.refresh does not throw EntityNotFoundException for removed entity
EntityManager.refresh does not throw EntityNotFoundException for removed entity
-------------------------------------------------------------------------------
Key: HHH-4880
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4880
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager
Affects Versions: 3.5.0-Beta-4
Environment: Hibernate 3.5.0-Beta-4, JBoss AS trunk (from which 6.0.0.M2 will be
released), Sun Java 1.6
Reporter: jaikiran
The EntityManager.refresh method says this:
/**
* Refresh the state of the instance from the database,
* overwriting changes made to the entity, if any.
*
* @param entity
* @throws IllegalStateException if this EntityManager has been closed
* @throws IllegalArgumentException if not an entity
* or entity is not managed
* @throws TransactionRequiredException if invoked on a
* container-managed entity manager of type
* PersistenceContextType.TRANSACTION and there
is
* no transaction.
* @throws EntityNotFoundException if the entity no longer
* exists in the database
*/
public void refresh(Object entity);
JBoss EJB3 testsuite has a testcase which currents tests that this method works as
expected
http://anonsvn.jboss.org/repos/jbossas/projects/ejb3/trunk/testsuite/src/...
In short, the testcase does this:
MyEntity e = manager.find(MyEntity.class, id);
local.removeEntity(e.id);
try
{
manager.refresh(e);
}
catch (EntityNotFoundException e1)
{
return; // correct
}
Starting 3.5.0-beta-4 of hibernate, this test fails with the following (unexpected)
exception:
Caused by: org.hibernate.AssertionFailure: object must be non-null.
