[hibernate-dev] Regression after upgrade to 4.1.7.Final

Hi, We just upgraded to Hibernate 4.1.7.Final (from 4.1.6.Final) and we have a pretty bad regression with 4.1.7 and Hibernate Search 4.1.1. We have the following stack trace when saving an object: Caused by: org.hibernate.HibernateException: Error while indexing in Hibernate Search (before transaction completion) at org.hibernate.search.backend.impl.EventSourceTransactionContext$DelegateToSynchronizationOnBeforeTx.doBeforeTransactionCompletion(EventSourceTransactionContext.java:186) at org.hibernate.engine.spi.ActionQueue$BeforeTransactionCompletionProcessQueue.beforeTransactionCompletion(ActionQueue.java:662) at org.hibernate.engine.spi.ActionQueue.beforeTransactionCompletion(ActionQueue.java:307) at org.hibernate.internal.SessionImpl.beforeTransactionCompletion(SessionImpl.java:607) at org.hibernate.engine.transaction.internal.jdbc.JdbcTransaction.beforeTransactionCommit(JdbcTransaction.java:105) at org.hibernate.engine.transaction.spi.AbstractTransactionImpl.commit(AbstractTransactionImpl.java:175) at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:75) at org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:512) ... 47 more Caused by: java.lang.NullPointerException at org.hibernate.engine.internal.StatefulPersistenceContext.getLoadedCollectionOwnerOrNull(StatefulPersistenceContext.java:851) 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:1799) at org.hibernate.collection.internal.AbstractPersistentCollection$4.doWork(AbstractPersistentCollection.java:524) at org.hibernate.collection.internal.AbstractPersistentCollection.withTemporarySessionIfNeeded(AbstractPersistentCollection.java:212) at org.hibernate.collection.internal.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:520) at org.hibernate.collection.internal.AbstractPersistentCollection.read(AbstractPersistentCollection.java:125) at org.hibernate.collection.internal.PersistentBag.iterator(PersistentBag.java:266) at org.hibernate.search.engine.spi.AbstractDocumentBuilder.appendContainedInWorkForInstance(AbstractDocumentBuilder.java:296) at org.hibernate.search.engine.impl.WorkPlan$PerEntityWork.processContainedIn(WorkPlan.java:525) at org.hibernate.search.engine.impl.WorkPlan$PerClassWork.processContainedInAndPrepareExecution(WorkPlan.java:297) at org.hibernate.search.engine.impl.WorkPlan.processContainedInAndPrepareExecution(WorkPlan.java:144) at org.hibernate.search.backend.impl.WorkQueue.prepareWorkPlan(WorkQueue.java:135) at org.hibernate.search.backend.impl.BatchedQueueingProcessor.prepareWorks(BatchedQueueingProcessor.java:71) at org.hibernate.search.backend.impl.PostTransactionWorkQueueSynchronization.beforeCompletion(PostTransactionWorkQueueSynchronization.java:86) at org.hibernate.search.backend.impl.EventSourceTransactionContext$DelegateToSynchronizationOnBeforeTx.doBeforeTransactionCompletion(EventSourceTransactionContext.java:183) ... 54 more I don't know if it's something obvious or if you need a self contained test case to reproduce it. I haven't created a JIRA because I don't know if it's an incompatibility between Hibernate Search 4.1.1 and Hibernate 4.1.7 or a real bug (either in HHH or HSEARCH). Feel free to ping me for more information or any further action. Thanks. -- Guillaume
