Web Service Request works on EAP 6.0.x but throws SAXParseException in EAP 6.2.x

Issue

When I send in a web service request in to JBoss EAP 6.0.x it works but when I send the same request to JBoss EAP 6.2.x I get the following exception:

Caused by: com.sun.istack.SAXParseException2; lineNumber: 0; columnNumber: 0; unexpected element (uri:"http://webservice/service/MyWebService/data/schema", local:"operationName1"). Expected elements are <{}operationName1>,<{}operationName2>,<{}operationName3>
