[hibernate-dev] CGLIB

[Steve Ebersole]

Since it is really ASM for which we are interested in isolation, I  
guess we would take the cglib-nodep jar which 'bundles' ASM as  
net.sf.cglib.asm (perhaps via jarjar as well) and run jarjar on that  
to repackage net.sf.cglib -> org.hibernate.cglib (or some-such).  Is  
that your understanding as well?
