Gary D. Gregory moved COMMONSSITE-178 to VALIDATOR-501:
-------------------------------------------------------
Key: VALIDATOR-501 (was: COMMONSSITE-178)
Project: Commons Validator (was: Apache Commons All)
> DomainValidator accepts hyphens at start/end of domain name with Unicode
> characters
> -----------------------------------------------------------------------------------
>
> Key: VALIDATOR-501
> URL: https://issues.apache.org/jira/browse/VALIDATOR-501
> Project: Commons Validator
> Issue Type: Bug
> Reporter: Victoria Dimitrova
> Priority: Major
> Labels: BUG, validator
>
> The method `DomainValidator.getInstance().isValid()` returns `true` for
> invalid domain names that start or end with a hyphen when the domain name
> contains Unicode characters.
> This behavior is incorrect according to the domain name specifications (RFC
> 1035, RFC 5890), which do not allow:
> - Domain labels starting or ending with a hyphen (`-`)
> Test case that should pass but fails on version 1.10.0:
> {code:java}
> @Test
> void shouldBeInvalid()
> {
> assertAll(() ->
> assertFalse(DomainValidator.getInstance().isValid("-test.fr")),
> () -> assertFalse(DomainValidator.getInstance().isValid("-tést.fr")),
> () -> assertFalse(DomainValidator.getInstance().isValid("test-.fr")),
> () -> assertFalse(DomainValidator.getInstance().isValid("tést-.fr")));
> }
> {code}
