I just updated to HB 2.1rc1 from b6 and I am now getting the following exception when loading the hibernate.cfg file by my Context Listener.

INFO [ReflectHelper] reflection optimizer disabled for: com.bt.domain.model.bid.BuilderBidRequest, IllegalAccessError: null

StandardContext[/buildtrax]: Exception sending context initialized event to listener instance of class com.bt.business.common.StartupListener
java.lang.IllegalAccessError
at net.sf.cglib.core.ClassEmitter.setTarget(ClassEmitter.java:87)

This is basically all I am doing in my Context Listener.

// Configure Hibernate.
try {
new Configuration().configure().buildSessionFactory();
if (log.isDebugEnabled()) {
log.debug("Hibernate configuration completed.");
}
} catch (HibernateException h) {
log.fatal("Error configuring Hibernate!", h);
}

Then..

/**
* Gets the session factory instance.
*/
public static SessionFactory getSessionFactory() throws ServiceException {
if (sessionFactory == null) {
try {
Configuration cfg = new Configuration().configure();
sessionFactory = cfg.buildSessionFactory();
}
catch (HibernateException e) {
throw new ServiceException(e);
}
}
return sessionFactory;
}

The latter method is simple used by my DAO objects. I looked at the new features, but I did not see any information regarding the changes I would need to make to existing code or things that would naturally break with the new release. Everything compiles just fine.

Any ideas would be helpful.

I missed the removal of cglib.asm jar file. Its been my habit to remove all old jar files with new release ust in case. But I missed this one. Once it was removed. All ran just fine.

Sorry again.
