[Document Conversion Service JDK API] omit Parent ID missing from the answer units

[christianIreland]

When using the Watson SDK-API to submit documents to the Document Conversion Service, the Answer Units generated are missing the Parent ID.

The issue is easily reproducible, just by using the Watson SDK. A snippet of code is reported below:

private Answers convertDocumentToAnswer(File document,  String mediaType) throws FileNotFoundException {
        ServiceCall<Answers> answersCall;
        JsonObject dcsConfigJson = loadDCSConfiguration();
        answersCall = getCoversionService().convertDocumentToAnswer(document, mediaType, dcsConfigJson);
        return answersCall.execute();
    }

The issue is reproducible in all the JDK versions available.
Java SDK version is 1.8.0_101

Apparently, the reason why the issue is happening is the ParentID field missing from the class Answer part of Answers

an example of the conversion is reported below:

{
  "answer_units": [
    {
      "content": [
        {
          "media_type": "text/html",
          "text": "\u003cp\u003ethis is the first chapter\u003c/p\u003e"
        },
        {
          "media_type": "text/plain",
          "text": "this is the first chapter"
        }
      ],
      "id": "cdf93476-f4ba-40eb-af1e-cdf96bb19ff0",
      "title": "First Chapter",
      "type": "h1"
    },
    {
      "content": [

        },
        {
          "media_type": "text/plain",
          "text": "this is the second chapter"
        }
      ],
      "id": "d19d0ef9-ec74-4816-b48a-82bb76e8568b",

Thanks @christianIreland.
Looks like direction might also be missing from Answers.AnswerUnits
