> We are trying to upgrade to a newer version of CXF in a web service client application. Most of our services are running fine on the new version, but one of the services are failing consequently with the following exception (line numbers depending a bit on CXF version tested):

> I have tried to pinpoint exactly where this error originates from, but this seems to be "buried" deep into the implementation details. I would have loved to submit a pull request, but I suspect any suggested change from my part would cause other things to fail.
> However, I can try to summarize my findings, so someone with knowledge of the CXF source code hopefully can dig deeper into this:
> - I seems to me that the problem is related to the fact that the cxf-codegen-plugin consider the operation to have one *in-out parameter*, and not one in and one out parameter. I do not understand why, but maybe someone with deeper understanding of WSDLs can explain?
> - The problem also seems to be related to the fact that we prefer *BARE mode* over WRAPPED mode. If I configure the cxf-codegen-plugin to generate WRAPPED mode Java stubs, it all works. Changing to WRAPPED mode for this particular service seems to be the only workaround I can think of; without changing the WSDL.
> - The problem also has something to do with the use of *implicit soap (response) header* in the WSDL. If I remove the implicit soap header from the WSDL, everything works fine.
> I have attached a zip-file containing the WSDL in question (simplified and anonymized) and a failing test case. The test case is inspired by the system tests in cxf-systests-uncategorized, and may be added to this module when/if the bug is fixed.
> Note: The WSDL may seem a bit strange (I did not make it), but it appears to be valid (at least SoapUI says it is). We are just implementing a client application to a legacy system, so changing the WSDL is not an option (unless proved invalid....)
> I have tested a few different versions of CXF, and the problem seems to have appeared in version 2.7.12 (works with 2.7.11). I am not sure what changes that may have caused this to break, but I suspect changes related to CXF-5676. This particular issue is the only one in 2.7.12 (that I could find) related to implicit SOAP headers.
