          Issue Type: Bug
      Security Level: Public (Everyone can see)

         Environment: Windows OS, JDK 5.x , hibernate as ORM

Hi
I am getting the following exceptions , when trying to use loadtime instrumentation of my dao objects which are getting loaded using hibernate.
The exception occurs both in Habanero and Alegrias . I need to use Jboss Pojo cache in fron of hibermnate, not as second level cache.

Please help.

(Also note that , I was trying to use AOPC to do compile time instrumentation. It had no problem. But as we have FAT/SMART clients in our application,
and need to transfer serialized copies of the POJOs stored in cache, I was having a problem as the classes weaved with AOPC were having the class-interceptors as their field. So I was getting a Not-Serializable exception .  I wanted to check with load time instrumentation to avoid that problem)
