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:
