Summary: [HHH-7629] Initialize PersistentCollection with fetchType LAZY returns NPE
Key: HIBERNATE-139
URL: https://issues.jboss.org/browse/HIBERNATE-139
Project: Hibernate Integration
Issue Type: Support Patch
Reporter: Ricardo Martinelli Oliveira
Assignee: Steve Ebersole
@JoinTable(name = "JOIN_TABLE", joinColumns = { @JoinColumn(name = "JOIN_TABLE_ID", referencedColumnName = "ID") }, inverseJoinColumns = { @JoinColumn(name = "ENTITY_ID", referencedColumnName = "ID") })
@ManyToMany(fetch = FetchType.LAZY)
private Set<JoinTable> aProperty;
When fetching this entity, and after initialize, I get all the valid attribute values but the aProperty is defined as PersistenceCollection.
This collection is not intialized yet. When I initialize this collection as follow:
(PersistentCollection) entity).forceInitialization();
Or
Hibernate.initialize(entity);
I got NullPointerException:
Caused by: java.lang.NullPointerException
at org.hibernate.engine.internal.StatefulPersistenceContext.getLoadedCollectionOwnerOrNull(StatefulPersistenceContext.java:790)
at org.hibernate.event.spi.AbstractCollectionEvent.getLoadedOwnerOrNull(AbstractCollectionEvent.java:75)
at org.hibernate.event.spi.InitializeCollectionEvent.<init>(InitializeCollectionEvent.java:36)
at org.hibernate.internal.SessionImpl.initializeCollection(SessionImpl.java:1803)
at org.hibernate.collection.internal.AbstractPersistentCollection.forceInitialization(AbstractPersistentCollection.java:489)
at org.hibernate.Hibernate.initialize(Hibernate.java:77)
When I check source code of class org.hibernate.engine.internal.StatefulPersistenceContext.getLoadedCollectionOwnerOrNull(StatefulPersistenceContext.java:790)
CollectionEntry ce = getCollectionEntry( collection );
790 if ( ce.getLoadedPersister() == null ) { 791 return null; // early exit... 792 }
Looks like the CollectionEntry ce is null. This collection entry is fetched from collectionEntries.get(coll);
// Identity map of CollectionEntry instances, by the collection wrapper
121 private IdentityMap<PersistentCollection, CollectionEntry> collectionEntries;
I checked Jboss docs, it mentioned the way to initilialize the collection is as I have done above.

[JBoss JIRA] (AS7-5101) Support unmanaged deployments in the console
by Brian Stansberry (JIRA)
Brian Stansberry created AS7-5101:
-------------------------------------
Summary: Support unmanaged deployments in the console
Key: AS7-5101
URL: https://issues.jboss.org/browse/AS7-5101
Project: Application Server 7
Issue Type: Feature Request
Components: Console
Reporter: Brian Stansberry
Assignee: Heiko Braun
The AS supports the notion of "unmanaged" deployments, where, rather than uploading the deployment content to the server, which then serves it from its internal content repo, instead the filesystem path to the content is provided and the content is served directly from that location.
This mechanism is particularly helpful with exploded deployments; it's what the filesystem deployment scanner uses when it detects an exploded deployment.
The CLI supports this via the --unmanaged flag that can be passed to the "deploy" command.
The console should expose this functionality as well.
If this were used in a managed domain, it's the responsibility of the user to ensure that the content is available at the provided path on all relevant hosts in the domain. EAP itself takes no responsibility for managing that content.
