what do you mean by "by default" ? is there a way to force AJ to do it ?

Greetings,
I am trying to put a joinpoint on a java.util.ArrayList class.
But on runtime the advice is never executed.
Did I miss something, or is it simply impossible to put a joinpoint on a
Java API class ?
Here is my aspect code :
pointcut grouik() : get(* java.util.ArrayList.*);
after() returning() : grouik() {
System.out.println("grouik");
}
This join point attempts to call reads of any fields of an ArrayList
object. If that's what you meant, by default, AJ won't insert advice in
JDK classes. This was primarily because of Sun's licensing restrictions
about modifying the byte code of the JVM and libraries. There are
workarounds documented on the net. The licensing restriction is more or
less going away since Java is transitioning to open source.
However, if you meant "match all field reads in my classes of type
ArrayList", it would be
pointcut grouik(): get (java.util.ArrayList ...*.*)
(The three dots mean: ".." any packages, arbitrarily deep + "." the
usually package separator - before the first "*" for matching any
class/interface)
Hope that helps.

Thanks in advance.
