------------------------------------
Why is an issue such as this still open after more than 2 years?
I have the exact same problem. I have an eagerly loaded association for a collection of
entities. For performance reasons I would like to create an internal Set for some property
of these entities. Either the setter or the @PostLoad would be a clean and simple place to
create this, yet Hibernate won't let me because of this silly exception.
I now have to code a very ugly workaround, where I manually track stuff and build this Set
after the first to its setter. This works, but it's verbose, ugly and brittle.

Key: JBAS-5474
URL: https://jira.jboss.org/browse/JBAS-5474
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: EJB3
Affects Versions: JBossAS-4.2.2.GA
Environment: Win XP SP2, Java 1.5.0_15-b04
Reporter: Stefan Lindner
Assignee: Emmanuel Bernard
Attachments: Child.java, Parent.java, PostLoadTest.java
I have a bean with a @OneToMany relation mapping like
private List<TherapieeinheitBean> therapieeinheiten;
@OneToMany(
cascade = {CascadeType.REFRESH},
fetch = FetchType.EAGER,
mappedBy="therapiekatalog"
)
with FetchType.EAGER and a simnple @PostLoad like
@PostLoad
public void postLoad() {
System.out.println("!!!!!!!!!! postLoad !!!!!!!!!!");
System.out.print("size: " + therapieeinheiten.size());
}
When an entity of this bean is loaded JBoss trows
org.hibernate.LazyInitializationException: illegal access to loading collection
at
org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:341)
at
org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86)
at org.hibernate.collection.PersistentBag.iterator(PersistentBag.java:249)
at
de.visiodesk.therapiekatalog.TherapiekatalogBean.postLoad(TherapiekatalogBean.java:170)
.
.
.
and prints the messages
WARN [LoadContexts] fail-safe cleanup (collections) :
org.hibernate.engine.loading.CollectionLoadContext@2c8ce9<rs=Ingres-ResultSet[18523]>
WARN [CollectionLoadContext] On CollectionLoadContext#cleanup,
localLoadingCollectionKeys contained [206] entries
afterwards. The PostLoad method should be called after the data was completely loaded. Is
there a workaround for this Problem? I found some other ressources on the net where peole
had the same problem, but I saw no resolution, no hint, no workaround.
