*
* </ul>
*
* <p>If the given address includes a JNDI directory URL as

*
* <p>If the URL path part of the <code>JMXServiceURL</code> was
* empty or a single slash (<code>/</code>), then the RMI object
* will not be bound to a directory. Instead, a reference to it
* will be encoded in the URL path of the RMIConnectorServer
* address (returned by {@link #getAddress()}). The encodings for
* <code>rmi</code> are described in the package documentation for
* {@link javax.management.remote.rmi}.</p>
*
* <p>The behavior when the URL path is neither empty nor a JNDI

* is implementation defined, and may include throwing

* or when it is started.</p>
