The number of stories in JIRA is not the same in the reported output

[DicksengA]

Example, An epic has 100 stories but the report only links 50 stores.

Found that in JerseyJiraClient

 if (batchSize > 0) {
            target = target.queryParam("maxResults", batchSize);
 }
Response response = target.request().get();

When batch size is 0, response returned from is jira is maxResults 50, and total greater than 50. In my case total 72.
