Classcastexception seistub cannot be cast to org.apache.cxf.frontend.clientproxy exacttarget fuelsdk

[cqsapientu69896]

I am trying to use FuelSDK as an osgi bundle by embedding it in another bundle using embed dependency. While using the bundle I am getting this error in the logs - 

java.lang.ClassCastException: com.sun.xml.internal.ws.client.sei.SEIStub cannot be cast to org.apache.cxf.frontend.ClientProxy

I found these links -- http://cxf.547215.n5.nabble.com/wsdl2java-Set-Java-Version-td4301284.html

 where it is written to use a non-cxf client, but we cannot change fuelsdk's code.  Did anyone else face the same issue while integrating cxf with AEM? Any help is appreciated.

Thanks

The only related article we have for AEM/CFX is consuming a 3rd party WSDL using CFX generated proxy files -- http://scottsdigitalcommunity.blogspot.ca/2016/08/creating-aem-html-template-language.html

Notice at start - we have to modify sling props file.
