> If column count in CSV header is more or equal to MAXCOLUMNS option value then array index out of bound exception is thrown by the Univocity CSV parser. This is because while parsing the row, parser adds each row to an array and increments the index and after incrementing it performs one more operation using the incremented index value which leads to array index pf bound exception
