 Post subject: Javassist Enhancement failed

This program works with 3.2.1. Simply replacing the hibernate3.jar and adding the new
required jars in 3.3, the program throws org.hibernate.HibernateException: Javassist Enhancement failed:. Note that this is a multii-threaded app (and, yes, each app has it's own session -- remember this works in 3.2.1) and this error only occurs occasionally. Also, occasionally, rather than throwing this hibernate exception, the user object is returned as null, i.e. hibernate fails to instantiate it. This doesn't occur in the database due to not null and FK constraints in the user login name map table. This looks very much like a hibernate bug in the switch to javassist (or a bug in javaassist) as the NPE occurs in generated code. Anyone have any ideas? Any developers wish to comment?

Thanks,
Brian

Code between sessionFactory.openSession() and session.close():
much too much to include here. I've attempted to include the relevant lines
based on the stack trace included below.

excerpt from DefectProcessor (see stack trace):

readSession = sessionFactory.openSession();
writeSession = sessionFactory.openSession();
dbUtils = new DbUtils(userManager, writeSession);

----------------------------------------------------------------------------------------
excerpt from DbUtils (session == writeSession):

ArrayList<UserLoginNameMap> loginMaps =
(ArrayList) userManager._findInSession(UserLoginNameMap.class, filter, session, false);

----------------------------------------------------------------------------------------
public List _findInSession(Class clazz, Filter filter, Session session, boolean excludeDeletedObjects)
{
List objs = null;
Transaction tx = session.beginTransaction();

try
{
objs = objectDao.find(filter, null, session, clazz, excludeDeletedObjects);
}
finally
{
try { tx.rollback(); }
catch (Exception ex1) {}
}

return objs;
}

----------------------------------------------------------------------------------------------
public List find(Filter filter, Integer maxResults, Session session, Class clazz,
boolean excludeDeletedObjects)
{
Criteria criteria = session.createCriteria(clazz);
List<KeyValuePair> keyValuePairs = filter.getKeyValuePairs();

// exlude deleted items
if (excludeDeletedObjects) criteria.add(Restrictions.eq("softDelete", Boolean.FALSE));

// limit the result set
if (maxResults != null)
{
criteria.setFirstResult(0);
criteria.setMaxResults(maxResults);
}

//add the filter(s)
for (KeyValuePair keyValuePair : keyValuePairs)
{
addExpression(criteria, keyValuePair);
}

if (null != getDefaultOrder()) criteria.addOrder(getDefaultOrder());

return criteria.list();
}

This is the code I run.
jdk 1.5
The latest Hibernate viersion downloaded last week
My sql 5.0 without connection pool.

Code:
    public static void loadData(String id,String id2) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
//        Customer customer1 = (Customer) session.get(Customer.class, id);//        System.out.println("customer1 = " + customer1);

        CustomerOrder order = (CustomerOrder)session.get(CustomerOrder.class,id2) ;
        System.out.println("order = " + order);
        System.out.println("order.getCustomer() = " + order.getCustomer());
//        System.out.println("order3.getCustomer() .getName() = " + order3.getCustomer().getName());
        session.getTransaction().commit();
    }


If I load a Customer class befor load the order, following code runs ok,
but if i comment the code "Customer customer1 = (Customer) session.get(Customer.class, id);" there will throw a exception

Code:
Hibernate: select customeror0_.id as id1_0_, customeror0_.orderNumber as orderNum2_1_0_, customeror0_.customer as customer1_0_ from CustomerOrder customeror0_ where customeror0_.id=?

I thought this error may have some relationship with the lazy feature.

Changing the constructor from private to public fixed it for me.

Has anyone discovered what was wrong with this?
My classes have public constructors.

Try providing public constructors without args.
