PersistantBag.initializeFromCache can be intercepted by CollectionLoadContext.getLoadingCollection and so corrupt the collection
--------------------------------------------------------------------------------------------------------------------------------
Key: HHH-2881
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2881
Project: Hibernate3
Issue Type: Bug
Environment: Hibernate Entity Manager 3.3.1 GA, oracle,
Reporter: Pavol Zibrita
It can occur that while PersistenBag.initializeFromCache is called to populate the collection from cache, the collection is populated also from CollectionLoadContext.getLoadingCollection, and so, the collection is filled with more data than needed. As the initializeFromCache uses direct access to the property this.bag, it will continue loading the collection. Here is the stack trace of what happens:

Small fix to the PersistantBag has resolved this issue, however I cannot tell if it is correct by some hibernate principles:
public void initializeFromCache(CollectionPersister persister, Serializable disassembled, Object owner)
throws HibernateException {
Serializable[] array = (Serializable[]) disassembled;
int size = array.length;
List<Object> elements = new ArrayList<Object>(size);
for ( int i = 0; i < size; i++ ) {
Object element = persister.getElementType().assemble( array[i], getSession(), owner );
if ( element!=null ) {
elements.add( element );
}
}
beforeInitialize( persister, size );
for ( Object element : elements ) {
this.bag.add( element );
}
}
Difference is, before the this.bag.add(element) was called in first cycle, where the line of getting the element could cause reinitializing the collection and filling it up. There are various possibilities how to fix the problem, but I don't know if the fix is at the right place!

Merge fails on complicated data structure because of cycle references

On complicated object structure, hibernate was unable to merge it correctly because of attaching ID's to the new objects in the tree of the persistent entity. Hibernate cannot cope with cyclic references in this case and it fails with:

Transient fields are not ignored in Hibernate. I got an "Property has an unbound type" exception and found no workaround.
Entity:

}
public K getDummyField() {
return dummyField;
}
public void setDummyField(K dummyField) {
this.dummyField = dummyField;

EntityTransaction tx = em.getTransaction();
tx.begin();
Dummy a = new Dummy();
em.persist(a);

[Hibernate-JIRA] Created: (HHH-2355) CGLIBLazyInitializer can not access a public member if parent class is not public
by Daniel Beland (JIRA)
CGLIBLazyInitializer can not access a public member if parent class is not public
---------------------------------------------------------------------------------
Key: HHH-2355
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2355
Project: Hibernate3
Type: Bug
Versions: 3.2.1
Reporter: Daniel Beland
In hibernate 3.2.1, CGLIBLazyInitializer cannot acces a public method if it has been inherited from a parent class that is not public.
Let's say we have a class A, modifier = default (package) with a public method getName() (and setName(String name)).
Then I create a public class B that extends A.
in my code I can retrieve B from the database:
B b = session.load(B.class, new Integer(1), LockMode.NONE);
I receive b with all the values set correctly (So at this point, Hibernate was able to use the method setName() correctly).
In my code if I then try to use b.getName(), I receive and error:
java.lang.IllegalAccessException-->Class org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer can not access a member of class A with modifiers "public"
But I am not trying to access A.getName(), but B.getName() (which is a public method in a public class).
This was working perfectly with Hibernate 2.1.7c and 3.1.3.
The full information about my problem can be found here: http://forum.hibernate.org/viewtopic.php?t=969453
