> When using env.readCsvFile(filename), if a line in the CSV file has an empty last field, the line ends with a comma. This triggers an exception in GenericCsvInput.parseRecord():
> 			// check valid start position
> 			if (startPos >= limit) {
> 				if (lenient) {
> 					return false;
> 				} else {
> 					throw new ParseException("Row too short: " + new String(bytes, offset, numBytes));
> 				}
> 			}
> Setting the parser to lenient would cause the last field to be left as null, rather than setting its value to "".
> The parser should accept empty values for the last field on a row.
