Unable to combine Resource Archive (RAR) <dependencies> and <exclusions> directives in jboss-deployment-structure.xml without <exclusions> being ignored

I have an EAR file where for a WAR sub-deployment I want to declare a startup dependency on another Resource Archive (RAR) deployment (in my application's case, the WebSphere MQ RAR - but I have recreated this with other Resource Archives) and also have a module exclusion (in this case, on the org.apache.log4j module so that my application can use internally defined Log4J configuration).

The jboss-deployment-structure.xml for the EAR looks like this :-

<jboss-deployment-structure>
    <sub-deployment name="application.war">
        <dependencies>
            <module name="deployment.wmq.jmsra.rar" />
        </dependencies>
        <exclusions>
            <module name="org.apache.log4j" />
        </exclusions>
    </sub-deployment>
</jboss-deployment-structure>

When I startup the EAR, the <dependencies> directive for the sub-deployment takes effect - the WAR is not started until the WebSphere MQ RAR is available. However, my <exclusions> directive is ignored and the application Log4J configuration is not used.

If I restructure the jboss-deployment-structure.xml and remove the <dependencies> directive from the sub-deployment :-

<jboss-deployment-structure>
    <sub-deployment name="application.war">
        <exclusions>
            <module name="org.apache.log4j" />
        </exclusions>
    </sub-deployment>
</jboss-deployment-structure>

The <exclusions> directive is interpreted correctly and the application Log4J configuration is used.

Also, if I go the other way and remove the <exclusions> directive and put the the <dependencies> directive back :-

<jboss-deployment-structure>
    <sub-deployment name="application.war">
        <dependencies>
            <module name="deployment.wmq.jmsra.rar" />
        </dependencies>
    </sub-deployment>
</jboss-deployment-structure>

The <dependencies> continues to be interpreted correctly and the WAR does not start until the dependency is available.

It would just seem that I can't combine the two directives and have them both be interpreted correctly. I have tried changing the order of defining them in the file but that (unsurprisingly) didn't make a lot of difference.

I have also tried this with the dependency being any other type of deployment - EAR, WAR, JAR, etc - and in those cases everything works correctly. It seems to only be an issue if the dependency is a Resource Archive.

I've also given it a go on a recent 7.2.0 Nightly (3 Jan 2013) and it is also exhibiting the same behaviour.

I have attached a sample application to replicate this behaviour. It uses the Apache Jackrabbit RAR (since the WebSphere MQ one is not distributable) as the Resource Archive dependency and creates 2 EAR files that are trying to use log4j to log to a file - one with just the <exclusions> directive and one with both the <dependencies> and <exclusions> directives. See the README file in the zip for more details.
