No ClassLoaders found for: sun.reflect.GeneratedMethodAccess

[lawc]

Hi,

I have a pointcut defined on a method to be intercepted.

The method can be called from a stateless EJB or a MDB. Interception happens succesfully on the method invocation in both cases.

However, once invoked via the MDB, the exception below is thrown everytime the method is called from the stateless EJB.

I am using JBoss 4.2.2. I have tried several versions of JBoss AOP (1.5.5 to 2.1.1), but get the same behaviour.

I would appreciate any help in resolving this problem.
