Hibernate Validator + Spring: incorrect message on validation error

Question

I wrote a custom Hibernate validation constraint for Money class:

@Target({METHOD, FIELD, ANNOTATION_TYPE})
@Retention(RUNTIME)
@Constraint(validatedBy = MoneyLimitedValidator.class)
@Documented
public @interface MoneyLimited {
    String message() default "{error.validation.money.limited}";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

It works fine except error message. I see very strange behaviour: resource bundle found and message resolved by name, but it wrapped into special chars which usually appears if message can't be resolved by name:

??Incorrect sum value._en_EN??

Here Incorrect sum value. is a correct message, which is accepted by name error.validation.money.limited. Originaly my message looks so:

error.validation.money.limited = Incorrect sum value.

I tried to remove {} braces from message name into MoneyLimited#message(), but nothing changes (even more strange).

I specified my validation message bundle as described in this answer:

<annotation-driven validator="validator" />
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="validationMessageSource" ref="messageSource"/>
</bean>

So the question is: how to fix message?

I'm using Spring Framework 3.2.4.RELEASE and Hibernate Validator 4.3.1.Final.

Solution

I'm found the reason of double resolving. I didn't mentioned before, that I'm using Thymeleaf as template engine (which is using SpringEL). There are an useful snippet in example app, which I just copy-paste (shame on me) and forgot about:

<div class="errors" th:if="${#fields.hasErrors('*')}" th:fragment="validationErrorTpl">
    <ul>
        <li th:each="err : ${#fields.errors('*')}" th:text="#{${err}}">Input is incorrect</li>
    </ul>
</div>

As you can see ${err} variable enclosed in #{}, which is actually resolving message from bundle. So with braces in validation constraint, message was resolved twice: on annotation level and in view template.
