Class level validation error messages are not sent to the client anymore [DATAREST-926]

René Reitmann opened DATAREST-926 and commented

We have just upgraded spring boot from 1.3.6 to 1.4.1 (=> data-rest from 2.4.4 to 2.5.3) and see the following issue: We do only use JSR-303 validations and have configured the ValidatingRepositoryEventListener to validate with LocalValidatorFactoryBean on beforeCreate and on beforeSave. After the upgrade, class level JSR-303 validation errors are not sent to the client anymore. However, field errors are sent to the client.

As mentionened here https://jira.spring.io/browse/DATAREST-832 there is (and has always been) a bug in RepositoryConstraintViolationExceptionMessage which only serializes field errors and no global errors. If I rollback spring boot to 1.3.6 (data-rest to 2.4.4) I can see that class level validation errors result in field errors with empty field name and are therefore serialized by RepositoryConstraintViolationExceptionMessage.

I assume that there has been a change in Spring core which causes class level validation errors to result in global errors and not in field errors anymore. Do you know something about such a change?

Affects: 2.5.4 (Hopper SR4)
