Hi Guys,
I got NullPointerException from org.hibernate.engine.StatefulPersistenceContext.

My hibernate dependency is as follows:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.5.6-Final</version>
</dependency>

The exception stack is below:
org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Error while committing the transactionremoteInvocation: methodName:getRestaurantStoreScores, clientVersion:1.1.7, userId:99c6ebe9-ac91-4a2b-a34d-53c44bb84b24, parameters:[[33aae146-3a5e-4a5f-bf63-71d8966fc387]]invalid remote invocation made by 90.210.209.30

I am looking at the line 1401 of StatefulPersistenceContext.java file:
Code:
1396   public void replaceDelayedEntityIdentityInsertKeys(EntityKey oldKey, Serializable generatedId) {
1397      Object entity = entitiesByKey.remove( oldKey );
1398      EntityEntry oldEntry = ( EntityEntry ) entityEntries.remove( entity );
1399      parentsByChild.clear();
1400
1401      EntityKey newKey = new EntityKey( generatedId, oldEntry.getPersister(), getSession().getEntityMode() );
1402      addEntity( newKey, entity );


so the possible null object here could be oldEntry, right? Could anyone tell me when oldEntry can become null? What can i do to fix the problem?

your help will be highly appreciated, Thanks
Cheng Wei
