- * <p>RMI object used to forward an MBeanServer request from a client

- * connected to an RMI connector.</p>
- *
- * <p>User code does not usually refer to this interface. It is
- * specified as part of the public API so that different
- * implementations of that API will interoperate.</p>
- *
- * <p>To ensure that client parameters will be deserialized at the
- * server side with the correct classloader, client parameters such as
- * parameters used to invoke a method are wrapped in a {@link
- * MarshalledObject}. An implementation of this interface must first
- * get the appropriate class loader for the operation and its target,
- * then deserialize the marshalled parameters with this classloader.
- * Except as noted, a parameter that is a
- * <code>MarshalledObject</code> or <code>MarshalledObject[]</code>
- * must not be null; the behavior is unspecified if it is.</p>
- *
- * <p>Class loading aspects are detailed in the companion document
- * <em>JMX Remote API</em>, which completes this documentation.
- * It should be available as a PDF document in the same place as this
- * Javadoc specification.</p>
- *
- * @since 1.5
- * @since.unbundled 1.0
