Xerces module missing dependency in EAP 6

Issue

• Application has a dependency to the xerces static module like below.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
    <deployment>
        <dependencies>
            <module name="org.apache.xerces" services="import" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

• When deploying the application got below error.

07:53:20,550  ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/frevvo]] (ServerService Thread Pool -- 203) JBWEB000287: Exception sending context initialized event to listener instance of class com.gauss.forms.servlet.FrevvoContextListener: java.lang.NoClassDefFoundError: org/apache/xml/resolver/CatalogManager
  at org.apache.xerces.util.XMLCatalogResolver.init(XMLCatalogResolver.java:537) [xercesImpl-2.9.1.redhat-5.jar:2.9.1.redhat-5]

• This missing CatalogManager class lives in the xml-resolver module provided by jboss. However the xerces module does not declare a dependency on it.

<module xmlns="urn:jboss:module:1.1" name="org.apache.xerces">
    <resources>
        <resource-root path="xercesImpl-2.9.1.redhat-5.jar"/>
        <!-- Insert resources here -->
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <!-- <module name="org.apache.xml-resolver" /> IF I ADD THIS DEPEDENCY HERE IT WORKS -->
    </dependencies>
</module>
