| * @bug 4149366 |
| * @summary The class loader used to load classes for parameter types sent in |
| * an RMI call to an activatable object should delegate to the class loader |
| * that loaded the class of the activatable object itself, to maximize the |
| * likelihood of type compatibility between downloaded parameter types and |
| * supertypes shared with the activatable object. |
