Enhance SoapDecoder by using Content Type from Response as Mime Type

By sending a soap request to an external service, i've found that the response of that soap call contains the Content-Type "multipart/related; type="application/xop+xml"; boundary=...".

The result is that the soap Message unmarshalling fails with some error "Unexpected content...".
I've fixed that by creating a copy of SoapDecoder and propagate the Content-Type of the response to the MessageFactory.
After that the Soap Envelope was unmarshalled as expected.

The relevant part that i've changed is:

final MimeHeaders mimeHeaders = new MimeHeaders();
final String contentType = response.headers().get("Content-Type").stream().collect(Collectors.joining(";"));
mimeHeaders.setHeader("Content-Type", contentType);
SOAPMessage message = MessageFactory.newInstance(soapProtocol)
                                    .createMessage(mimeHeaders, response.body().asInputStream());

Would be nice if it's possible to always use the Content-Type from the Response, but i don't know if there are any other pitfalls when doing that in general.

Kind regards,

Stefan

Start in SoapDecoder and trace how the HTTP response is passed to MessageFactory.newInstance(soapProtocol). Reproduce the multipart/related response with its Content-Type header, then verify that the header reaches SOAP message creation and the envelope unmarshals successfully.
