[aspectj-users] aspect on a java API class

[ldelaforge@xxxxxxx]

Hi all,

I am (still) trying to put a joinpoint on a java API class : java.math.BigDecimal
I try to do it with load time weaving LTW (with a JavaAgent)

My aspect is like this :
@Aspect
public class AppAspect {
    @After("execution(* java.math.BigDecimal.valueOf(..))")
                        public void afterBigDecimal(JoinPoint jp) {
                                System.out.println("grouik BigDecimal");
    }
}

And, because I know it is normally not authorized to do it,
I bypass the loading of the BigDecimal of the rt.jar, by bootloading an extracted java.math.BigDecimal.
I do it by adding in the JVM parameters -Xbootclasspath/p:"D:\...\target\test-classes\temp"
where ...\temp\ contains java\math\BigDecimal.class

But when I execute this, the advise is not executed...

Is the bypass a good solution ? If yes, why does it not working ? If no, is there another way ?

Thanks in advance.
