[hibernate-dev] CGLIB

[Steve Ebersole]

Our (default) dependency on CGLIB is starting to cause problems due to  
other libraries using newer versions of ASM (3.x) then the released  
versions of CGLIB use (2.x).  We have now been waiting about a year  
for a new CGLIB release to use these newer ASM APIs.  With 3.3 being  
eminent, we need to rectify this situation.

First, I am going to make javassist the default bytecode provider  
starting with Hibernate 3.3 (http://opensource.atlassian.com/projects/hibernate/browse/HHH-2506 
).

Next, we need to decide what to do with CGLIB moving forward.  This  
seems to be a dead project at this point.  From my recollection, the  
source control for CGLIB does in fact have support for ASM 3.x; so one  
option would be to do a build of it from HEAD.  However, none of us  
are really bytecode gurus, so thats probably not the best option.  The  
only other option I see is to simply deprecate the integration for  
CGLIB and recommend against its use.  Any other options we should  
explore here?
