#15 http-request creates empty content-type header

[Anonymous]

Hi!

While trying to interact with MarkLogic, I've found an issue with MorganaXProc that causes all our POST requests to fail. It seems that MorganaXProc adds an empty content-type header to its outbound HTTP requests, which some servers ignore and some do not.

Here's a test XProc to show the issue:

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc"
                xmlns:c="http://www.w3.org/ns/xproc-step"
                version="1.0"
                name="test-http-post">
  <p:http-request>
    <p:input port="source">
      <p:inline>
        <c:request href="http://localhost:9090"
                   method="post">
          <c:body content-type="application/xml">
            <test/>
          </c:body>
        </c:request>
      </p:inline>
    </p:input>
  </p:http-request>
  <p:sink/>
</p:declare-step>

To see the request headers, one can run nc to listen on localhost port 9090 like so:
nc -l 9090
Here' s what MorganaXProc sends:

chrodon 1016_% nc -l 9090
POST / HTTP/1.1
Content-Type: application/xml
content-type:
Content-Length: 9
Host: localhost:9090
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.2 (Java/1.8.0_101)

<test />

As can be seen, there are two "content-type" headers, one with the correct "application/xml" value, and one that is empty. I've tried to locate where the problem is created in the Java source code, but I could not really find it. Any help would be greatly appreciated.

Thanks,
Hans
