[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6960) NullPointerException in PreCollectionRemove Listener

NullPointerException in PreCollectionRemove Listener ---------------------------------------------------- Key: HHH-6960 URL: https://hibernate.onjira.com/browse/HHH-6960 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.0.0.Final Environment: Hibernate 4.0.0 to MySQL Reporter: Kevin Jordan Assignee: Gail Badner Fix For: 4.1.4 Attachments: hibernateBugProofWithSchema.zip, hibernateBugProof.zip I'm getting a NullPointerException on line 47 of EnversPreCollectionRemoveEventListenerImpl very consistently. I wasn't sure if it was due to lazy collections or not, but it seems that it fails if they're eagerly fetched or lazily fetched. I'm guessing it has something to do with getLoadedPersister() returning a null value since the comments for it say "This is only available late during the flush cycle". The stack trace is Quote: java.lang.NullPointerException at org.hibernate.envers.event.EnversPreCollectionRemoveEventListenerImpl.onPreRemoveCollection(EnversPreCollectionRemoveEventListenerImpl.java:47) at org.hibernate.action.internal.CollectionRemoveAction.preRemove(CollectionRemoveAction.java:143) at org.hibernate.action.internal.CollectionRemoveAction.execute(CollectionRemoveAction.java:104) at org.hibernate.engine.spi.ActionQueue.execute(ActionQueue.java:273) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:265) at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:188) at org.hibernate.event.internal.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:323) at org.hibernate.event.internal.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:52) at org.hibernate.internal.SessionImpl.flush(SessionImpl.java:1081) at org.hibernate.internal.SessionImpl.managedFlush(SessionImpl.java:315) at org.hibernate.engine.transaction.internal.jdbc.JdbcTransaction.beforeTransactionCommit(JdbcTransaction.java:101) at org.hibernate.engine.transaction.spi.AbstractTransactionImpl.commit(AbstractTransactionImpl.java:175) at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:73) ... 120 more
