title: @HeaderParam("Cookie") returns null when testing with curl -b "cookie:value"
body: <p>I have function</p>
  
  <pre><code>@POST
  @Consumes({ ExampleMediaTypes.PLAINTEXT_0_1_0, MediaType.TEXT_PLAIN, ExampleMediaTypes.SIMPLE_PROTOBUF_0_1_0, ExampleMediaTypes.SIMPLE_JSON_0_1_0, ExampleMediaTypes.STRUCTURED_JSON_0_1_0 })
  @Produces({ PredictionMediaTypes.PLAINTEXT_0_1_0 })
  @Path("/main")
  public ChunkedOutput&lt;String&gt; doPredict(ExamplesIterable examplesIterable,@HeaderParam("User-Agent") String userAgent, @HeaderParam("Cookie") String cookies) throws IOException {
      System.out.println("hello");
      System.out.println(cookies);
      System.out.println(userAgent);
      return new RequestHandler(executorService, exampleProcessorFactory).handleRequest(examplesIterable);
  }
  </code></pre>
  
  <p>That just prints cookie value, when I test it with : </p>
  
  <pre><code>curl -H "Content-Type:text/plain" -X POST -T /home/aleksander/bandit/daemon/test_cb.dat http://localhost:8080/vw-webservice-jersey/predict/main -v -b "cookieName:cookieValue;secondCookie:value"
  </code></pre>
  
  <p>I see :</p>
  
  <pre><code>hello
  null
  curl/7.35.0
  </code></pre>
  
  <p>What's the problem? Is this bad curl request or annotations mistake?</p>
