New convenience methods on Validator: void assertValid(Object o)/assertValidProperty(...)/assertValidValue(...) which throw a runtime ValidationException
---------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: BVAL-199
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-199
             Project: Bean Validation
          Issue Type: New Feature
          Components: spec-general
    Affects Versions: 1.0 final
            Reporter: Geoffrey De Smet


90% of the time we want to do:
{code}
Set<ConstraintViolation<Car>> constraintViolations = validator.validate(car);
if (constraintViolations.size() > 0) {
  throw new MyValidationException(decentErrorMessage);
}
{code}
>From http://docs.jboss.org/hibernate/stable/validator/reference/en/html_single/#validator-usingvalidator-validate


So why not supply a facade method to make it easy for us developers (especially those migrating from hibernate validator 3)?
{code}
  validator.assertValid(car);
{code}
That allows the bean validation to standarize the Exception too:
a ValidationException (or InvalidStateException or whatever you call it), which is of course a runtime exception.
That in turn, allows the front-end frameworks to deal with that exception more cleanly (give the user a clue why the business method failed when it imported that address without a street from an import addresses file).

Give special care to the message of that exception. It should clearly state at least 1 of the validations that failed (in english, not i18n)
so when we find such an exception in the log we can easily see what caused it.
