validateValue incorrectly reports java.lang.IllegalArgumentException: Invalid property path. There is no property listOfString in entity simple_bv_servlet.Person
-----------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: BVAL-175
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-175
             Project: Bean Validation
          Issue Type: Bug
    Affects Versions: 4.0.0.Alpha2
         Environment: HEAD of JSR-303 RI
            Reporter: Ed Burns

Calling validator.validateValue() seems to fail when it shouldn't.

Consider this pojo:

8<----------------------------------

package simple_bv_servlet;

import java.util.List;
import javax.validation.constraints.NotNull;

public class Person {

    @NotNull
    private String firstName;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    @NotNull
    private String lastName;

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    private List<String> listOfString;

    public List<String> getListOfString() {
        return listOfString;
    }

    public void setListOfString(List<String> listOfString) {
        this.listOfString = listOfString;
    }

}

8<----------------------------
And consider this selvlet which validates this pojo in its doGet() impl.

        if (violations.isEmpty()) {
            out.print("<p>");
            out.print("No ConstraintViolations found.");
            out.print("</p>");
        } else {

        }

        Person person = new Person();

        out.print("<h1>");
        out.print("Validating invalid person instance using validate.");
        out.print("</h1>");

        violations = beanValidator.validate(person);

            out.print("No ConstraintViolations found.");
            out.print("</p>");

                out.print("ConstraintViolation: message: " + curViolation.getMessage() +
                        " propertyPath: " + curViolation.getPropertyPath());
                out.print("</p>");
            }
        }

        out.print("<h1>");
        out.print("Validating valid person.");
        out.print("</h1>");

        person.setFirstName("John");
        person.setLastName("Yaya");

        violations = beanValidator.validate(person);

                out.print("ConstraintViolation: message: " + curViolation.getMessage() +
                        " propertyPath: " + curViolation.getPropertyPath());
                out.print("</p>");
            }
        }

        out.print("</body></html>");

    }

}

8<------------------------

The call to 

        Set<ConstraintViolation<Person>> violations =
                beanValidator.validateValue(Person.class, "listOfString", value);

causes this exception to be thrown:

java.lang.IllegalArgumentException: Invalid property path. There is no property listOfString in entity simple_bv_servlet.Person

But I say, doch, there is such a property on the Person.  

This is new behavior in 4.0.0.Beta2, and it's breaking Glassfish.

Thanks,

Ed
