sahvx655-wq opened a new pull request, #411:
URL: https://github.com/apache/commons-validator/pull/411

   Noticed while validating IBANs read line by line out of a file: a value with 
a trailing newline came back INVALID_LENGTH and one with a leading space 
UNKNOWN_COUNTRY, although both validate once the surrounding whitespace is 
stripped.
   
   1. validate(String) is the only validation method here and isValid delegates 
to it, yet it never normalises its argument, unlike CodeValidator.validate and 
the AbstractNumberValidator/AbstractCalendarValidator parse paths which all 
trim first.
   2. the raw string is handed to getValidator, which reads the first two 
characters as the country code, so a leading space selects the wrong code and 
any surrounding whitespace also trips the fixed-length check, leaving the 
returned IBANValidatorStatus misleading rather than VALID.
   
   Trimmed once at the top of validate and ran the country lookup, length, 
pattern and check digit against that value; the null path is unchanged as 
getValidator already tolerates null.

   - [x] Write unit tests that match behavioral changes, where the tests fail 
if the changes to the runtime are not applied. This may not always be possible, 
but it is a best practice.
   - [x] Write a pull request description that is detailed enough to understand 
what the pull request does, how, and why.
