We are using a proxy for each entity (bytebuddy), also we created a Tuplizer and an Instantiator for Hibernate.
This works for loading an entity from a DB, for creating a new entity and for modifying an entity but not for deleting. Create, load and modify seams seems to use *SessionImpl.contains(entityName, object)* and delete uses *SessionImpl.contains(object)*. Both methods are trying to load an EntityPersister (Line 2058 and 2025) but the method without the entityName parameter (Line 1982) tries to load the persister by class-name instead of the entity-name.
Bugfix is on line "*getSessionFactory().getMetamodel().entityPersister*"
Current:
{code:title=SessionImpl.java|borderStyle=solid}
@Override
public boolean contains(Object object) {
//...
if ( entry == null ) {
if ( !HibernateProxy.class.isInstance( object ) && persistenceContext.getEntry( object ) == null ) {
// check if it is even an entity -> if not throw an exception (per JPA)
try {
final String entityName = getEntityNameResolver().resolveEntityName( object );
if ( entityName == null ) {
throw new IllegalArgumentException( "Could not resolve entity-name [" + object + "]" );
}
getSessionFactory().getMetamodel().entityPersister( object.getClass() );
}
catch (HibernateException e) {
throw new IllegalArgumentException( "Not an entity [" + object.getClass() + "]", e );
}
}
return false;
}
//...
}
{code}
Fixed:
{code:title=SessionImpl.java|borderStyle=solid}
@Override
public boolean contains(Object object) {
//...
if ( entry == null ) {
if ( !HibernateProxy.class.isInstance( object ) && persistenceContext.getEntry( object ) == null ) {
// check if it is even an entity -> if not throw an exception (per JPA)
try {
final String entityName = getEntityNameResolver().resolveEntityName( object );
if ( entityName == null ) {
throw new IllegalArgumentException( "Could not resolve entity-name [" + object + "]" );
}
getSessionFactory().getMetamodel().entityPersister( entityName );
}
catch (HibernateException e) {
throw new IllegalArgumentException( "Not an entity [" + object.getClass() + "]", e );
}
}
return false;
}
//...
}
{code}
I am trying to create a simple test for that.. |
