Wildfly ClassNotFoundException when using new module dependency

Wildfly logs are blowing up on startup with several ClassNotFoundException's after adding a new module for Log4j2. It kind of seems like it's looking in that module for other Java EE classes that my newly defined module has nothing to do with.

Here is one of the Exceptions:

    17:52:57,865 WARN  [org.jboss.modules] (ServerService Thread Pool -- 52) Failed to define class org.apache.logging.log4j.core.net.AbstractJMSReceiver in Module "org.apache.log4j2:main" from local module loader @1c323a (finder: local module finder @125871f (roots: /usr/local/share/wildfly/modules,/usr/local/share/wildfly/modules/system/layers/base)): java.lang.LinkageError: Failed to link org/apache/logging/log4j/core/net/AbstractJMSReceiver (Module "org.apache.log4j2:main" from local module loader @1c323a (finder: local module finder @125871f (roots: /usr/local/share/wildfly/modules,/usr/local/share/wildfly/modules/system/layers/base)))

At the moment I am just trying to deploy my persistence unit archive to make sure I've mapped everything correctly, and this archive depends on Log4j2. In the META-INF directory of my persistence archive I have a jboss-deployment-structure.xml that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="org.apache.log4j"/>
        </exclusions>
        <dependencies>
            <module name="org.apache.log4j2">
                <imports>
                    <include path="META-INF"/>
                </imports>
            </module>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

My module is defined by the following directory structure in Wildfly:

$WILDFLY_HOME/modules/org/apache/log4j2/main/
    log4j-api-2.0-rc1.jar
    log4j-core-2.0-rc1.jar
    module.xml

And finally my module.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.apache.log4j2">
    <resources>
        <resource-root path="log4j-api-2.0-rc1.jar"/>
        <resource-root path="log4j-core-2.0-rc1.jar"/>
    </resources>
    <dependencies>
        <module name="com.lmax.disruptor"/>
        <module name="javax.api"/>
        <module name="javax.servlet.api"/>
    </dependencies>
</module>

It seems very odd that wildfly would even be trying to look for javax.jms.MessageListener at this point, and even more so that it is looking for it "from org.apache.log4j2:main"

Does anyone have any idea how to resolve this exception?

WildFly isn't trying to look for javax.jms.MessageListener the org.apache.logging.log4j.core.net.AbstractJMSReceiver is. I don't know how many other dependencies log4j2 has, but you'll at least need to add javax.jmx as a dependency.
