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
