| Hi,
I have found one issue related with ScrollableResults and fetching child collection for version 4.3.10.
I’m getting NPE from StatefulPersistenceContex line 756 because ce is null: public Object getLoadedCollectionOwnerOrNull(PersistentCollection collection) {
final CollectionEntry ce = getCollectionEntry( collection );
if ( ce.getLoadedPersister() == null ) { return null; } ... I have child collection PairingComplement –s. Single PairingComplement is using in method hashCode other collection Positions related with PairingComplement and fetched after PairingComplement –s ( example hql:
Select p from Pairing p left outer join fetch p.complements c left outer join fetch c.positions ) Seems that order is the reason why StatefulPersistenceContext collectionEntries does not contains Positions collection. java.lang.NullPointerException
