I cannot easily reproduce yet, but the NPE is at:
{code}
Caused by: java.lang.NullPointerException
at org.hibernate.collection.internal.AbstractPersistentCollection$1.doWork(AbstractPersistentCollection.java:164)
at org.hibernate.collection.internal.AbstractPersistentCollection$1.doWork(AbstractPersistentCollection.java:157)
{code}
Code lines:
{code:java}
protected boolean readSize() {
if ( !initialized ) {
if ( cachedSize != -1 && !hasQueuedOperations() ) {
return true;
}
else {
final boolean isExtraLazy = withTemporarySessionIfNeeded(
new LazyInitializationWork<Boolean>() {
@Override
public Boolean doWork() {
final CollectionEntry entry = session . getPersistenceContext() . getCollectionEntry( AbstractPersistentCollection . this );
if ( entry != null ) {
final CollectionPersister persister = entry.getLoadedPersister();
if ( persister.isExtraLazy() ) { // persister is null here
if ( hasQueuedOperations() ) {
{code}
