This complete program works for me. Can you perhaps try code style
instead of annotation style?
The pointcut is as I wrote in my previous email.

@interface RuleSet {}
@Retention(RetentionPolicy.RUNTIME)
@interface Category {}
aspect Watcher {
pointcut computationOfHealth(): execution(public List<Health>
getHealth(AggregateInfo));
before(): computationOfHealth() {System.out.println("advice on
getHealth");}
pointcut category(Category category): execution(@Category * *(..)) &&
cflowbelow(computationOfHealth()) && @annotation(category);
before(Category category): category(category) {
System.out.println("advice on @Category tagged method running in
cflow of getHealth");
System.out.println("category="+category);
}
pointcut ruleset(RuleSet rs, Category c): execution(@RuleSet * *(..))
&& cflowbelow(category(c)) && @annotation(rs);
before(RuleSet rs, Category c): ruleset(rs,c) {
System.out.println("advice on @RuleSet tagged method running in
cflow of something tagged @Category which is in the cflow of
getHealth");
System.out.println("ruleset="+rs+" category="+c);
}
}
public class AA {
@Category
public void computationMethod() {
System.out.println("@Category tagged method running");
doSomething();
}
@RuleSet
public void doSomething() {
System.out.println("@RuleSet tagged method running");
}
public List<Health> getHealth(AggregateInfo ai) {
System.out.println(">getHealth");
doSomething(); // not advised, not in the cflow of an @Category
tagged thing
computationMethod(); // called in the cflow of getHealth()
doSomething(); // not advised, not in the cflow of an @Category
tagged thing
System.out.println(">getHealth");
return Collections.emptyList();
}
public static void main(String[] args) {
AA aa = new AA();
aa.computationMethod();
Object o = aa.getHealth(null);
}
}
class AggregateInfo {}
class Health {}
