JBoss 6 AS with AOP throws StackOverflowError

I am using JBoss 6 AS and trying to add via AOP an interceptor to the classes in some package from a deployed application. This is the scenario:

I have an app.jar that contains the classes to which I want to add advices. This JAR also has some EJBs (ejb-jar.xml, jboss.xml).

I created my on JBoss interceptor like this :

package util;
import org.jboss.aop.joinpoint.Invocation;
import org.jboss.aop.joinpoint.MethodInvocation;
public class MyInterceptor implements org.jboss.aop.advice.Interceptor {
    @Override
    public Object invoke(Invocation invocation) throws Throwable {
        long startTime = System.currentTimeMillis();
        try {
            return invocation.invokeNext();
        } finally {
            long endTime = System.currentTimeMillis() - startTime;
            System.out.println("MyInterceptor : " + endTime);
            if (invocation instanceof MethodInvocation) {
                MethodInvocation mi = (MethodInvocation) invocation;
                String clazz = "";
                String method = "";
                try {
                    clazz = mi.getTargetObject().getClass().toString();
                    method = mi.getMethod().getName();
                } catch (Throwable e) {
                    System.out.println("Error when trying to get target info");
                }
                System.out.println("MyInterceptor : " + endTime);
            }
        }
    }

    @Override
    public String getName() {
        return "MyInterceptor";
    }
}

I created a jboss-aop.xml file that contains:

<?xml version="1.0" encoding="UTF-8"?>
<aop xmlns="urn:jboss:aop-beans:1.0">
    <interceptor name="MyInterceptor"  class="util.MyInterceptor"/>
    <bind pointcut="execution(* my.app.*->*(..))">
        <interceptor-ref name="MyInterceptor"/>
    </bind>
</aop>

I have set enableLoadTimeWeaving (bootstrap/aop.xml)
I have pluggable-instrumentor.jar in the right place (JBOSS/bin)
I have started the server with the option -javaagent:pluggable-instrumentor.jar
I have created a JAR file interceptor.jar where I put MyInterceptor.class and in its META-INF I've placed the jboss-aop.xml file

Now, that being said, the problem is that when I run my application and some method from any class from my.app package is being called the interceptor seems to intercept the call but it throws a nasty StackOverflowError. This is a part of my error stack:

Basically what happens is that these four lines are being thrown until StackOverflowError gets raised:

If anyone had some similar problem any help would be appeciated!

Solution

Well i found the problem ... i put the interceptor on the same package my.app and not in util ... so eventually it was calling itself endlessly until the stack was full . So ... my bad
