It's probably an empty line or comment line in the CSV or something like that. The error means that there is no 2nd value on that row (nextLine[1] is the second value). Check your file and print nextLine[0] and you will see the mistake. nextLine[0] will contain the whole row. Make sure you tell openCSV to use the poper separator, escape character etc.
