| * so we can actually create an AMXClientImpl simply by using the MBeanServer |
| * from the mom: this is useful for testing). |
| * <P> |
| * Note that this version of the AMXMBeanInterface API provides a generic get/set API that |
| * is identical to DynamicMBean, except that it only throws unchecked exceptions. |
| * This is far more convenient in practice than the JMX-standard checked exceptions. |
