turn on debug for com.noelios.restlet package doesn't seem to work

[dev dev]

I add the following to the  log4j.xml file and run one of the sample
applications and i don't see any debugs generated from the
com.noelios.restlet package but i do see the debugs from the sample
applications (so log4j is working as expected).

<logger name="com.noelios.restlet">
        <level value="DEBUG"/>
    </logger>
