When reading an Excel 2007 sheet with rows with more than 702 columns the method XSSFRow.getLastCellNum() reports 702 instead of the correct number.

The problem seems to be in the class XSSFCell. The method parseCellNum(String) does not work for more then two characters:

    protected static short parseCellNum(String r)
    {
        r = r.split("\\d+")[0];
        if(r.length() == 1)
            return (short)(r.charAt(0) - 65);
        else
            return (short)((r.charAt(1) - 65) + 26 * (r.charAt(0) - 64));
    }
