@PostLoad -> LazyInitializationException: illegal access to loading collection ond a @OneToMany with FetchType.EAGER

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.
