net.sf.cglib.core.CodeGenerationException: what does usually mean

[Srinath Perera]

Hi All; 

Am getting this net.sf.cglib.core.CodeGenerationException:  quite
regulerly. I know that means something wrong with the GBean I am
trying to start! but spending long times to find where is the error.

Is there any way to get more error messages? or  may be should write a
"Gbean verifier" to  check for the conditions and give better error
messages!
Thought?
Srinath
