Default Java client does not support Content-Type "application/xml"

I have a swagger.yaml with a post method that produces application/json and which consumes XML. Here's an excerpt:

    post:
      summary: Store a model.
      description: Stores the XML content of the specified model.
      consumes:
        - application/xml;charset=UTF-8
      parameters:
        - name: model
          in: body
          description: The model XML you want to store
          schema:
            type: string
          required: true

I generated the Java client from the swagger.yaml using swagger-codegen-cli-2.2.1.jar and the --lang java option. I did not specify a --library option. (I doubt it's relevant but, just in case, I also specified these options in an associated json config file: apiPackage, groupId, artifactId and artifactVersion.)

However when I issue a POST request with an XML string as input I get this error in the client:

com.mycompany.myapi.ApiException: Content type "application/xml;charset=UTF-8" is not supported
        at com.mycompany.myapi.ApiClient.serialize(ApiClient.java:889)
        at com.mycompany.myapi.ApiClient.buildCall(ApiClient.java:1105)
        at com.mycompany.myapi.client.DefaultApi.modelsPostCall(DefaultApi.java:523)
        at com.mycompany.myapi.client.DefaultApi.modelsPostWithHttpInfo(DefaultApi.java:544)

The generated method in com.mycompany.myapi.ApiClient looks like this:

    /**
     * Serialize the given Java object into request body according to the object's
     * class and the request Content-Type.
     *
     * @param obj The Java object
     * @param contentType The request Content-Type
     * @return The serialized request body
     * @throws ApiException If fail to serialize the given object
     */
    public RequestBody serialize(Object obj, String contentType) throws ApiException {
        if (obj instanceof byte[]) {
            // Binary (byte array) body parameter support.
            return RequestBody.create(MediaType.parse(contentType), (byte[]) obj);
        } else if (obj instanceof File) {
            // File body parameter support.
            return RequestBody.create(MediaType.parse(contentType), (File) obj);
        } else if (isJsonMime(contentType)) {
            String content;
            if (obj != null) {
                content = json.serialize(obj);
            } else {
                content = null;
            }
            return RequestBody.create(MediaType.parse(contentType), content);
        } else {
            throw new ApiException("Content type \"" + contentType + "\" is not supported");
        }
    }

In my case obj is a String. It looks like you don't support application\xml. Is this true? If so, how soon can we expect a fix please? Alternatively can you recommend a workaround I can use? I don't mind hacking the generated code to make it work until a proper fix is released.

Start with the generated ApiClient.java serialize method shown in the report and compare its handling of application/json with application/xml;charset=UTF-8. Reproduce the POST from the swagger.yaml excerpt using swagger-codegen-cli 2.2.1, then verify that the generated client accepts the XML request body without raising the unsupported-content-type error.
