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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
