   //~ Constructors ===================================================================================================
   public LogoutEvent(Authentication authentication) {       super(authentication);   }
}

Code:
lt;!-- ===================== LOGOUT FILTER ==================== --gt;

lt;bean id=quot;logoutFilterquot; class=quot;org.acegisecurity.ui.logout.LogoutFilterquot;gt;
lt;constructor-arg value=quot;/quot; /gt; lt;!-- ucl redirected to after logout --gt;
lt;constructor-arggt;
lt;listgt;
lt;ref bean=quot;myLogoutHandlerquot;/gt;
lt;ref bean=quot;rememberMeServicesquot;/gt;
lt;bean class=quot;org.acegisecurity.ui.logout.SecurityContextLogoutHandlerquot;/gt;
lt;/listgt;
lt;/constructor-arggt;
lt;/beangt;

lt;bean id=quot;myLogoutHandlerquot; class=quot;edu.cornell.birds.is.module.security.listener.LogoutEventBroadcasterquot;gt;
lt;/beangt;This is a good solution for logout event
