Hi [again], :(

I get the following error when switching from 2.1 beta 5 to 2.1 rc with the new CGLIB2 jar:

Exception in thread "main"

Same code worked before ...

You might check the faq http://www.hibernate.org/74.html and search for CGLIB2 in this forum. There have been several issues reported. I ran into problems caused by conflicts between CGLIB1 and CGLIB2. I ended up removing CGLIB support from the other application.

Same story - while I had both CGLIB2 & old CGLIB (from HB 2.0.3) in the classpath, I was getting same exception.
