For some reason if class have some optional field and other regular field,
valueContext for every field is using OptionalValueUnwrapper to unwrap and thowing cast exception since it is trying cast everyfield into option
[V validatedValue = (V) valueContext.getCurrentValidatedValue()|https://github.com/hibernate/hibernate-validator/blob/e90fea5f5704b1b1f8c657a51fc2f9bde6f8380f/engine/src/main/java/org/hibernate/validator/internal/engine/constraintvalidation/ConstraintTree.java#L446]
{code:java}
public class KafkaProducerFactory extends KafkaClientFactory {
static final int DEFAULT_BROKER_PORT = 9092;
@NotNull
@NotEmpty
private String name;
@NotEmpty
private ImmutableSet<InetSocketAddress> bootstrapServers =of();
private Acknowledgement acknowledgement = ALL;
@NotNull
@UnwrapValidatedValue
private Optional<CompressionType> compression = Optional.of(CompressionType.NONE);
}
{code}
I tired below code to validate
{code}
Set<ConstraintViolation<T>> invalids = Validation.byProvider(HibernateValidator.class).configure().buildValidatorFactory().getValidator().validate(this);
{code}
and
{code}
Set<ConstraintViolation<T>> invalids =
Validation.buildDefaultValidatorFactory().getValidator().validate(this);
{code}
Edited: Added stack trace
{code:java}
