Muga Nishizawa commented on JASSIST-28:
---------------------------------------

I'm sorry, it seems that the above jar file is broken... 
Please checkout source files of javassist in CVS repository, build them, and then try your test program again.  But, the performance of your system with javassist would be slower than with cglib still.  

 I have been finding the cause of the performance bottlenecks.
