DigitsValidator and EANValidator are not serializable.
------------------------------------------------------

                 Key: HV-71
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-71
             Project: Hibernate Validator
          Issue Type: Bug
          Components: validators
    Affects Versions: 3.1.0.GA
            Reporter: benoit heinrich


Hi all,

If you try to serialize a DigitsValidator and EANValidator validator class instance, then you get a nice:

java.io.NotSerializableException: org.hibernate.validator.DigitsValidator
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
        at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1375)
        at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1347)
        at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1290)
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1079)


An easy way to reproduce it is to run the following unit test:

public class ValidatorTest {
	@Test(dataProvider = "getValidators")
	public void testValidatorSerialization(Validator<?> validator) throws IOException {
		OutputStream os = new ByteArrayOutputStream();
		new ObjectOutputStream(os).writeObject(validator);
	}
	
	@DataProvider(name = "getValidators")
	public Object[][] getValidators() {
		return new Object[][] {
				{new AssertFalseValidator()},
				{new AssertTrueValidator()},
				{new CreditCardNumberValidator()},
				{new DigitsValidator()},
				{new EANValidator()},
				{new EmailValidator()},
				{new FutureValidator()},
				{new LengthValidator()},
				{new MaxValidator()},
				{new MinValidator()},
				{new NotEmptyValidator()},
				{new NotNullValidator()},
				{new PastValidator()},
				{new PatternValidator()},
				{new RangeValidator()},
				{new SizeValidator()},
			};
	}
}

To fix it you should simply make the two classes implementing Serializable.
