Hello Guys, A unit test added in revision 16012 is failing during our builds. The test I'm talking about is org.hibernate.validation.engine.groups.GroupTest .testGroupSequenceFollowedByGroup(). When I debugged, the iterator defined in line 281 always has the constraint violation for phoneNumber before that of defaultCreditCard. When I exchanged the locations of the asserts, the test succeeded, but of course I don't think that this is a good solution, since I'm sure that the tests run successfully on other machines. Regards Alaa Nassef
