* <p>RMI object used to forward an MBeanServer request from a client
* to its MBeanServer implementation on the server side. There is one
* Remote object implementing this interface for each remote 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
* <a href="{@docRoot}/../technotes/guides/jmx/JMX_1_4_specification.pdf">
* JMX Specification, version 1.4</a> PDF document.</p>
*
* <p>Most methods in this interface parallel methods in the {@link
* MBeanServerConnection} interface. Where an aspect of the behavior
* of a method is not specified here, it is the same as in the
* corresponding <code>MBeanServerConnection</code> method.
*
* @since 1.5

* Notice that we omit the type parameter from MarshalledObject everywhere,
