Session Listeners confusion?

[Sunny Jain]

Please help me to understand the answer of this question.
Source of question: Self created for understanding.
This is the piece of code in Servlet:

 
 HttpSession session = request.getSession();
 session.setAttribute("test", new SessionTest());
 session.setAttibute("test",new SessionTest());
 --> Session Migrated to another JVM 
 session.invalidate();  
 

This is the code of SessionTest class:

 
public class SessionTest implements 
                        HttpSessionListener,
                        HttpSessionAttributeListener,
                        HttpSessionBindingListener,
                        HttpSessionActivationListener {


   /*
    * HttpSessionListener(non-Javadoc)
    * @see javax.servlet.http.HttpSessionListener#sessionCreated(javax.servlet.http.HttpSessionEvent)
    */
   public void sessionCreated(HttpSessionEvent event){
   System.out.println("1");
   
   }
   
   public void sessionDestroyed(HttpSessionEvent event){
   System.out.println("2");
   }
   
   /*
    * HttpSessionAttributeListener(non-Javadoc)
    * @see javax.servlet.http.HttpSessionAttributeListener#attributeAdded(javax.servlet.http.HttpSessionBindingEvent)
    */
   public void attributeAdded(HttpSessionBindingEvent event){
   System.out.println("3");
}
   
  public void attributeReplaced(HttpSessionBindingEvent event){
  System.out.println("4");
}
  
  public void attributeRemoved(HttpSessionBindingEvent event){
  System.out.println("5");
}
   
  /*
   * HttpSessionBindingListener(non-Javadoc)
   * @see javax.servlet.http.HttpSessionBindingListener#valueBound(javax.servlet.http.HttpSessionBindingEvent)
   */
   public void valueBound(HttpSessionBindingEvent event){
   System.out.println("6");
   }
   
   public void valueUnbound(HttpSessionBindingEvent envent){
   System.out.println("7");
  }
   
   /*
    * HttpSessionActivationListener(non-Javadoc)
    * @see javax.servlet.http.HttpSessionActivationListener#sessionWillPassivate(javax.servlet.http.HttpSessionEvent)
    */
   public void sessionWillPassivate(HttpSessionEvent evnet){
   System.out.println("8");
   }
   public void sessionDidActivate(HttpSessionEvent event){
   System.out.println("9");
   }
}
   

What will be the output ??
I think answer should be
16337489275
or 16334789257
