JOnAS 5.3M5 and Servlet 3.0

Hi:

When deploying a WAR containing a 3.0 Servlet, JOnAS 5.3M5 (with =
tomcat7)  throws a NPE (see stack trace below).
My web.xml looks like this:

<web-app xmlns=3D"http://java.sun.com/xml/ns/javaee" =
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation=3D"http://java.sun.com/xml/ns/javaee =
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	metadata-complete=3D"true" version=3D"3.0">

	<display-name>Console</display-name>
	<description>Console</description>

        <servlet>
                <servlet-name>TimerServlet</servlet-name>
                =
<servlet-class>org.ow2.sirocco.cloudmanager.utils.LoadTimers</servlet-clas=
s>
                <load-on-startup>100</load-on-startup>
        </servlet>

</web-app>

Any idea what I've done wrong ?
Is there an example of Servlet 3.0 running under JOnAS 5.3 available =
somewhere ?=20
