             Summary: Merge Validation Fails With Chained Constructor
                 Key: OPENJPA-2279
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2279
             Project: OpenJPA
          Issue Type: Bug
          Components: validation
    Affects Versions: 2.2.0
         Environment: java 1.6
            Reporter: Roger Keays


The following simple test fails

   em.merge(new Customer("Park Lane");

when there is a chained constructor and validation like this:

    public Customer() {
        this(null);
    }
    public Customer(String street) {
        address = new Address();
        address.street = street; // annotated @NotNull
    }

OpenJPA validation is calling the first constructor during merge or validation
and is trying to validate an invalid object, even though the orginal WAS valid.

The stacktrace is

Caused by: javax.validation.ConstraintViolationException: A validation constraint failure occurred for class "testcase.openjpa.Address".
