22   *  The <code>RecoveryListener</code> is a marker interface for the <i>Recovery</i>
23   *  service.  Servers do not need to implement this interface, when the recovery
24   *  service is specified in the <i>applications.xml</i> file.  This is since server
25   *  will use the recovery service automatically.  However, some servers may wish to
26   *  provide some control over the shutdown procedure implemented within the recovery
27   *  layer.  Such servers must implement the <code>ShutdownListener</code> interface,
28   *  which provides a <code>shutdown()</code> method.
