    Description

      When trying to convert "0085" with NumberUtils.createInteger(String) an NumberFormatException is thrown.

      This is because the leading 0 causes the String to be evaluated as an Octal, 8 is not a valid octal.

      However NumberUtils#isNumber(String) evaluates to true, even so it cannot be converted.
