Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'

Question

I would like to store birthdate so I chose date at MySQL, when I create my entities based in my database, it turns out like this:

import java.util.Date;

    // ..code
    @NotNull(message="fill you birthdate")
    @Temporal(TemporalType.DATE)
    private Date birthdate;

But when I try to persist it gives me this error:

Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'. Please refer to embedded ConstraintViolations for details.

What am I doing wrong here ? I was reading something about define time zone in Google, I'm from Brazil, how should I do that ?

EDIT

package entity;

import java.io.Serializable;
import javax.persistence.*;

I got the same problem, but after hours looking for the answer, Finally I Found it.... You should edit your AbstractFacade.java class and add this code

public void create(T entity) {

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set<ConstraintViolation<T>> constraintViolations = validator.validate(entity);
    if(constraintViolations.size() > 0){
        Iterator<ConstraintViolation<T>> iterator = constraintViolations.iterator();
        while(iterator.hasNext()){
            ConstraintViolation<T> cv = iterator.next();
            System.err.println(cv.getRootBeanClass().getName()+"."+cv.getPropertyPath() + " " +cv.getMessage());

            JsfUtil.addErrorMessage(cv.getRootBeanClass().getSimpleName()+"."+cv.getPropertyPath() + " " +cv.getMessage());
        }
    }else{
        getEntityManager().persist(entity);
    }
}

Now this method will alert you which property and why it fails the validation. I hope this works for you, as it does for me.
