> If I unpack the war and remove
> wicket-examples/WEB-INF/lib/mx4j-3.0.1.jar the application
> launches alright.
> This error happens because Jetty already provides:
> * jetty/lib/management/mx4j-3.0.1.jar
> * jetty/lib/management/mx4j-tools-3.0.1.jar
> So we should maybe avoid to package those jars in WEB-INF/lib when building the wicket-examples WAR
