Basically Struts 2 always creates a new instance of the Action for each request. With all the confusion and threading problems that reusing Servlets caused, the Struts 2 developers decided it would be much safer to remove that part of the learning curve by using a new Action for each request. The overhead is minimal, but you have to be aware this is happening so that you don't put a bunch of initialization code in your actions.
