[aspectj-users] Re: thisJoinPoint.getThis() documentation

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Are you using a "call()" join point? In which case "this" will always be
null in a static method. Perhaps you should be using "getTarget()" e.g.

public class Main {

      public void test () {
            System.out.println("? test()");
      }

      public void instanceMethod () {
            test();
      }

      public static void main(String[] args) {
            Main main = new Main();
            main.instanceMethod();
            main.test();
      }
}

public aspect Logging {

      pointcut callTest() :
            call(* test());

      before () : callTest () {
            System.out.println("? Logging.callTest() this=" + thisJoinPoint.getThis() + " target=" + thisJoinPoint.getTarget());
      }
}
