Within my EAR file I have a META-INF/jboss-deployment-structure.xml file to include module dependencies towards my lightweight EAR.

However, if I explicitly add the correct namespace declaration to this XML config file, JBoss EAP explodes.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2"
                            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                            xsi:schemaLocation="urn:jboss:deployment-structure:1.2 http://www.jboss.org/schema/jbossas/jboss-deployment-structure-1_2.xsd">
    <ear-subdeployments-isolated>true</ear-subdeployments-isolated>
    <deployment>
        <dependencies>
            <module name="org.apache.commons.logging" export="true"/>
            <module name="org.slf4j" export="true"/>
            <module name="org.apache.commons.codec" export="true"/>
            <module name="org.apache.commons.lang" export="true"/>
            <module name="org.joda.time" export="true"/>
            <module name="org.apache.santuario.xmlsec" export="true"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

gives me

java.util.NoSuchElementException: No child 'name' exists: java.util.NoSuchElementException: No child 'name' exists
    at org.jboss.dmr.ModelValue.requireChild(ModelValue.java:369)

One would at least expect that you can add the regular XML namespace declaration without running into trouble.

Is this a bug in EAP 6?
