Problem:

I have an application that was working fine under "version 3.0.3 , 08. May 2005", and I have no code referencing net.sf.*.

After updating libraries to version 3.1, I get an error when Hibernate is building it's session factory:

"CGLIB Enhancement failed: gov.alaska.ezdoc.ContentObject
java.lang.NoSuchMethodError: net.sf.cglib.proxy.Enhancer.setInterceptDuringConstruction(Z)V".

This seems logical because I do not have hibernate2.jar in the classpath, but why is something trying to access a class in "net.sf.*"?

Full stack trace below.

Hibernate version:

3.1

Name and version of the database you are using:

Debug level Hibernate log excerpt:

The net.sf is for cglib, which is still a sourceforge project. Check the versions of cglib between 3.0.3 and 3.1 and see if you have the correct version.

On checking between Hibernate 3.0.5 which uses cglib-2.1.jar , Hibernate 3.1 uses cglib-2.1.3.jar.
When upgrading, upgrade the related jar files as well.

Yes! This response chased me up the correct tree and I found the old versions in jboss-hibernate.deployer. Replacing the jar files there did NOT fix the problem, but removing the entire directory did.

The Hibernate 3.1 upgrade continues to cause NullPointer and ClassCast exceptions for me, but only after a Jboss "hot deploy". If I bounce JBoss after deploying an updated war or ear file, no problem.

Since this may be more related to JVM and Caching issues, I consider this question resolved.

I think there are more unresolved issues, however, that are resulting from the Hibernate 3.1 upgrade that did not appear in prior versions. I'll keep watching and asking.

Thanks!
