Hello,
I have mandatory field in object which I want to validate:
{code}
@NotNull
private final LocalDate datumHinfahrt;
{code}
But when I'm trying to validate it using the Hibernate Validator I receive an exception:
{code}
javax.validation.ValidationException: HV000041: Call to TraversableResolver.isReachable() threw an exception.

Problem is that {{Validator}} invokes {{hashCode()}} with {{null}} mandatory field. But purpose of validation is to check nullability of this field and produce a validation error. Current behavior is conceptually wrong from my point of view.
Thanks in advance!
