Yes, there is a way besides the reflection form mentioned by Cazzola... Try
exposing the running object as below:
public aspect T {
String around(A obj): execution(public String A.getName()) && this(obj){
String text = "advice";
if(obj instanceof B){
text = ((B)obj).super.getName();
}
System.out.println(text);
return proceed(obj);
}
}
