| 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. |
