I haven't been through the entire logic to see what happens in what order,
but this is before advice, so the test if(state==2) will see the value of
state *before* it is set. So you need both for state to be set to 2 and
then set to something else afterwards for the println to run.

If you really want this to be before advice, something like this should
work:

 	before(int x): set(* state) && args(x) {
 		if(x==2)
 			System.out.println("Matched."+this);
 	}

The if could be made a pointcut if you wanted, too.
