26 * @summary The class loader used to load classes for parameter types sent in
27 * an RMI call to an activatable object should delegate to the class loader
28 * that loaded the class of the activatable object itself, to maximize the
29 * likelihood of type compatibility between downloaded parameter types and
30 * supertypes shared with the activatable object.
