Module classloader ignores resource-root definition

[alllle]

I have a SAR created with the following structure:

-mysar.sar

   +---mylib.jar

   +---com

          +---mypackage

                   +---myclass

   +--META-INF

          +---jboss-deployment-structure.xml

In the jboss-deployment-structure.xml file, I have:

{code:xml}
<jboss-deployment-structure>
    <deployment>
        <resources>
            <resource-root path="mylib.jar" />
        </resources>
    </deployment>
</jboss-deployment-structure>
{code}

So I expect that myclass can find the classes inside the mylib.jar, but no, it can not.

Anyone know what is wrong?

Thanks,
