"java.lang.ClassCastException" when putting <classloading> configuration in jboss-web.xml

Issue

When we put classloading confirmation in jboss-web.xml, we get a java.lang.ClassCastException

<?xml version="1.0" encoding="UTF-8" ?>
<classloading xmlns="urn:jboss:classloading:1.0"
    domain="IsolatedDomain"
    parent-first="false"
    export-all="NON_EMPTY"
    import-all="true">
</classloading>
