Issue MULE-8350: After upgrade CXF to 2.7.15 some jaxws-client configurations fail when using a proxy.
When the service method receives a Holder OUT parameter and then a String, the string value is not received by the server. If the method returns void, then the value placed in the OUT parameter does not arrive the to client. See org.mule.module.cxf.HolderTestCase, method testClientProxyEcho3Holder.
