Undertow: Error initialize the net.jawr.web.servlet.JawrServlet with undertow

I'm deploying a OSGi WAB file on the latest WildFly 8.0.0.Alpha2-SNAPSHOT server. Can not initialize the JavascriptServlet from JAWR Bundle. Note: When I used the <extension module="org.jboss.as.web"/> insted of <extension module="org.wildfly.extension.undertow"/> it works.

Please see error trace below.

Thanks!
