I think this change was made to bring the impl in compliance with the
servlet
spec.

The javadocs of HttpSession.getLastAccessedTime() have this:

* Returns the last time the client sent a request associated with
* this session, as the number of milliseconds since midnight
* January 1, 1970 GMT, and marked by the time the container received the
* request.

Notice the "associated with this session".

Only if a request creates or resumes a session should the session's
lastAccessedTime
be updated.
