java.util.NoSuchElementException in type level validation using EclipseLink
---------------------------------------------------------------------------

                 Key: HV-524
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-524
             Project: Hibernate Validator
          Issue Type: Bug
          Components: validators
    Affects Versions: 4.2.0.Final
         Environment: EclipseLink 2.2.0
            Reporter: sinuhepop


When EclipseLink obtains an entity from database does a validation. It works ok with field level validators, but throws an exception with type level ones.

The problem is that SingleThreadCachedTraversableResolver sends an "empty" pathToTraversableObject to EL's BeanValidationListener, who finally fails when calling "pathToTraversableObject.iterator().next().getName()".

I don't know who (HV or EL) is responsible of the issue, but it worked with HV-4.0.2.GA.


Thanks for your effort.


Sinuhé.
