I was going through HFSJ 1st edition Q15.
Q:- Once a session has been invalidated, which HttpSession methods can be called on that session without throwing illegalState Exception?
Answer: - Since the servletContext survives, getServletContext can be called successfully on an invalid session.
I am not so clear why? if an object is invalid now...how and why getServletContext servives. Trying to access this should give null pinter exception or
Please clarufy this doubt

When you call invalidate()
The session ID no longer exists.
The attributes are removed from the session object.
