HttpServlet Basic question

[Anurag Gupta]

If you look at the definition of HttpServlet:

   
public abstract class HttpServlet extends GenericServlet implements Serializable

and its super class, the GenericServlet

    
public abstract class GenericServlet extends Object implements Servlet, ServletConfig, Serializable

Since GenericServlet implements Serializable, then whats the need for the HttpServlet to implement Serializable again?
Am I missing something here !!!
