The com.sun.xml.bind module depends on and exports four other modules, and those modules in turn are private and have no other dependents:

        <module name="com.github.relaxng" export="true" />
        <module name="com.sun.istack" export="true" />
        <module name="com.sun.xml.txw2" export="true" />
        <module name="com.sun.xsom" export="true" />

Task is to:

1) Write to wildfly-dev mail list to check for any projects that layer on WildFly that directly use these modules.
2) Write to jboss-layered-products (internal Red Hat) mail list to check for any products based on WF/EAP that directly use these modules.
3) Assuming no positive responses, make the artifacts from the above four modules direct artifacts of the com.sun.xml.bind module, add any needed module dependencies to con.sum.xml.bind, and get rid of those four modules.
