ClassLoaderUtils.setThreadContextClassloader attempts to set null class loader

Created a custom connector for a SOAP Service using CXF for Oracle Identity Manager using their Identity Connector Framework (ICF).  Their framework has a Context Class Loader "watcher" that detects  that the ClassLoaderUtils.setThreadContextClassLoader() method is attempting to set a "null" loader.  This happens when a call is made to invoke a SOAP message:

    public void testService() {

        try {

            IPersonnelManagement2014 port = getPersonnelManagementPort2014();

            PersonnelManagementViewUser2Response response = port.viewUser("xxxxx", "external", null, null, null, null);
