Wildfly 10.0.0.Final duplicates contents of <jsp-config> <url-pattern> directive in web.xml

Question

I have been successfully deploying an application on WildFly 8.2.1 and WildFly 9.0.2 versions with the following <jsp-config> directives in web.xml deployment descriptor:

<jsp-config>
<jsp-property-group>
<description>header and footer settings</description>
<url-pattern>/WEB-INF/view/*</url-pattern>
<url-pattern>/WEB-INF/error/*</url-pattern>
<include-prelude>/WEB-INF/jspf/header.jspf</include-prelude>
<include-coda>/WEB-INF/jspf/footer.jspf</include-coda>
</jsp-property-group>
</jsp-config>

This code fragment includes the contents of /WEB-INF/jspf/header.jspf at the beginning of each .jsp file and <include-coda>/WEB-INF/jspf/footer.jspf</include-coda> at the end of each .jsp file that matches the <url-pattern>.

But when I try to deploy this application with the same deployment descriptor in WildFly 10.0.0.Final, the contents of /WEB-INF/jspf/header.jspf and /WEB-INF/jspf/footer.jspf are included twice in each .jsp file that matches the <url-pattern>.

If I add another <url-pattern> line, then the contents of /WEB-INF/jspf/header.jspf and /WEB-INF/jspf/footer.jspf are included three times, and so on.

Any suggestion about this issue?

Is this a deployment descriptor issue or a configuration issue in the standalone.xml of WildFly 10.0.0.Final version?

This a confirmed bug in WildFly 10.
