From an email sent to the user's list 6/26/2003:
------------------------------------------
ajc 1.1 NPE when an aspect declares hashcode() as follows:

     interface Identifiable {
         void setId(Id id);
         Id getId();
     }
 
     aspect IdentifiableAspect {
         private Id Identifiable.id = null;
         public Id Identifiable.getId() {
 		return this.id;
 	  }
         public void Identifiable.setId(Id id) {
             this.id = id;
         }
 
         public int Identifiable.hashCode() {
             return (this.getId() == null)
                 ? super.hashCode()
                 : this.getId().hashCode();
         }
     }

A workaround for callers the compiler controls is to replace the declaration
with around advice:

     int around(Identifiable i): target(i)
         && call(public int hashCode())
     {
         return (i.getId() == null)
             ? proceed(i)
             : i.getId().hashCode();
     }
