Author: Guillaume Smet <guillaume.smet(a)gmail.com&gt; Date: 2017-11-07 (Tue, 07 Nov 2017) Changed paths: M engine/src/main/java/org/hibernate/validator/internal/util/DomainNameUtil.java M engine/src/test/java/org/hibernate/validator/test/internal/constraintvalidators/hv/EmailValidatorTest.java M engine/src/test/java/org/hibernate/validator/test/internal/constraintvalidators/hv/URLValidatorTest.java Log Message: ----------- HV-1516 Support punycode-encoded domain names and consecutive hyphens Consecutive hyphens are allowed except when they are in third and fourth position (reserved for xn--). For now we don't implement this restriction as I don't think it's worth the complexity for such a narrow case.
