ClassNotFoundException with Guice 2.0

The code below generates an error using Guice 2.0. With Guice 1.0 everything is fine. The JDK is Java 6 update 15.

public class App {
public static void main(String[] args) {
Guice.createInjector(new AbstractModule() {
@Override
protected void configure() {
// just testing
}
});
}
}


The error is:

What can be the problem?

Answer

You have missed to include a dependency jar with the class org.aopalliance.intercept.MethodInterceptor in the classpath.
