It is because the getDataSetWithParams(prams) method is truncating the last character in the auth_token. Here is the output for the getDataSetWithParams(params) method: Executing request: http://www.quandl.com/api/v1/datasets/FRED/GDP.json?trim_start=2012-09-30&auth_token=mytoke
A fix for this is to change the return statement in the getDataSetWithParams(prams) method in QuandlConnection class to the following:
return new QDataset(curl(baseUrl + params.get("source_code") + "/" + params.get("code") + ".json" + paramString.substring(0, paramString.length() - 1)), "json");
More specifcially, changing the paramString.substring(0, paramString.length() - 2)
to paramString.substring(0, paramString.length() - 1)

The following use of the getDatasetWithParams(params) method gave me an
