Should be a way to access the original field value at a set joint point built
into the language.

a possible solution is to add  getOriginalFieldValueAtAFieldSetJoinPoint() 
method to the thisJoinPoint interface.

a usage example would be:
after(Object newValue) returning : set( * *) && args(newValue)  {   
  Object oldValue = 
thisJoinPoint.getOriginalFieldValueAtAFieldSetJoinPoint() ;  
  if (!oldValue.equals(newValue) { 
firePropertyChangeEvent(oldValue,newValue,thisJoinPoint.getSignature());
   }
}
