ClassCastException on Deployment in Weblogic 10.3

Question

When I am deploying my application in Weblogic 10.3, I am getting below Exception.
weblogic.application.ModuleException:
com.ctc.wstx.stax.WstxInputFactory cannot be cast to javax.xml.stream.XMLInputFactory
Earlier I had no problem with Weblogic 8.1.

I have the exact same issue. I'm trying to deploy a project that uses CXF 2.1 which uses the StaX parser. Here's what I've tried to do:
In my weblogic.xml, I have the following set to prefer the libraries I have in my WEB-INF/lib:
<wls:weblogic-web-app xmlns:wls="http://www.bea.com/ns/weblogic/weblogic-web-app"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
http://www.bea.com/ns/weblogic/weblogic-web-app http://www.bea.com/ns/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
     <wls:context-root>PCRSubmittal</wls:context-root>
     <wls:weblogic-version>10.3</wls:weblogic-version>
     <wls:container-descriptor>
          <wls:prefer-web-inf-classes>true</wls:prefer-web-inf-classes>
     </wls:container-descriptor>
</wls:weblogic-web-app>Then I created a weblogic-application.xml that has the StaX parser defined as follows:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application
     xmlns:wls="http://www.bea.com/ns/weblogic/weblogic-application"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/javaee_5.xsd

     </wls:prefer-application-packages>
</wls:weblogic-application>When I deploy I get the following exception:
