> The `java.util.Formatter` format specifies support for field widths, argument indexes, or precision lengths of a field that relate to the variadic arguments supplied to the formatter. These numbers are specified by integers, sometimes negative. For argument index, it's specified in the documentation that the highest allowed argument is limited by the largest possible index of an array (ie the largest possible variadic index), but for the other two it's not defined. Moreover, what happens when a number field in a string is too large or too small to be represented by a 32-bit integer type is not defined.
> This fix adds documentation to specify what error behavior occurs during these cases. Additionally it adds an additional exception type to throw when an invalid argument index is observed.
> A CSR will be required for this PR.
