[Esapi-dev] Help regarding issue 251

Well it sure is a significant bug. So how to fix?

So what if you first take the string and parse it to a Date, and then
take the same Date and format it back to a String? Assuming the format
does not include the erroneous characters, you might be able to fail
on validation if the original and formatted Date string do not match.

This is how I'd first take it on.

Maybe look for an Apache date class that is more strict?

Thanks for looking at this.
