Hi,

Is it possible to instruct hibernate to use cglib instead of javassist in the new release (3.3.1) ????

Thanks in advance.

Yes, of course. There is a property named "hibernate.bytecode.provider" and it can take the values "cglib" or "javassist".

Code:

<property name="hibernate.bytecode.provider" value="cglib" /> <!-- value="javassist" -->

I've tested it and it works.
By the way, this can only be set in hibernate.properties, and not in the hibernate.cfg.xml.

The problem is that hibernate will use it own repack version. Is it possible to use the version that I can dowload from the cglib project???

Actually, that is a problem related to a maven shade plugin. This plugin repack cglib-nodep-2.1_3.jar file and also replace all dependencies from the classes. All references to net.sf.cglib are changed to org.hibernate.repackage.cglib. However, there is a string("[Lnet/sf/cglib/proxy/Callback") into Enhancer class that the shade plugin does not understand as valid reference for a class and can't change, so that problem occurs
