kaffe/kaffevm/access.c has this code:

   261          else if( same_package && !(target_flags & ACC_PRIVATE) )
   262          {
   263                  /* Package. */
   264                  slot_acc = 1;
   265          }

I am afraid this makes anything private in the target class T
accessible to the caller C if T and C are in the same package
and T is accessible to C.
