/**
 * Starts the core XMPP server. A bootstrap class that configures classloaders
 * to ensure easy, dynamic server startup.
 *
 * This class should be for standalone mode only. Openfire servers launched
 * through a J2EE container (servlet/EJB) will use those environment's
 * classloading facilities to ensure proper startup.<p>
 *
 * Tasks:<ul>
 *      <li>Unpack any pack files in the lib directory (Pack200 encoded JAR files).</li>
 *      <li>Add all jars in the lib directory to the classpath.</li>
 *      <li>Add the config directory to the classpath for loadResource()</li>
 *      <li>Start the server</li>
 * </ul>
 *
 * Note: if the enviroment property {@code openfire.lib.dir} is specified
 * ServerStarter will attempt to use this value as the value for openfire's lib
 * directory. If the property is not specified the default value of ../lib will be used.
