#289 Human Task API - getting payload values

My process is as follows -

Human task title = ApproveTheOrder for Commiskey

Test Instance -

Task is assisgned to user jcooper.

API to retrieve the above data -

    public String getTaskdetails(String user, String pwd) {
        System.out.println("getTaskdetails()");
