NPE in annotation processor ConstraintHelper.getName()
------------------------------------------------------

                 Key: HV-575
                 URL: https://hibernate.onjira.com/browse/HV-575
             Project: Hibernate Validator
          Issue Type: Bug
          Components: annotation-processor
    Affects Versions: 4.3.0.Beta1
         Environment: Java 1.6_31, Windows 7
            Reporter: Daniel Ford


First attempt to compile code base causes NPE from annotation processor.  I might be able to create a reproducible example if needed.
Thanks!
Dan
