 There is no need to require class-wp-admin-bar.php a second time. If
 you're extending it, then it's already loaded by the time the
 'wp_admin_bar_class' filter is fired.

 Test code:

 function check_wp_admin_bar_class( $class ) {
         class My_Admin_Bar extends WP_Admin_Bar {


         echo '<p>&nbsp;</p><p><pre>'; var_dump( class_exists(
 'My_Admin_Bar' ) ); echo '</pre></p>';
         return 'My_Admin_Bar';

 add_action( 'wp_admin_bar_class', 'check_wp_admin_bar_class' );
