---------------------------------------

             Summary: Bean validation is done twice in JAX-RS application
                 Key: WFLY-12668
                 URL: https://issues.jboss.org/browse/WFLY-12668
             Project: WildFly
          Issue Type: Bug
          Components: Bean Validation, EJB, REST
    Affects Versions: 18.0.0.Final, 17.0.1.Final
         Environment: OpenJDK 11, reproduced on Win10 and Ubuntu 18.x
            Reporter: Daniel Munzinger
            Assignee: Cheng Fang


If a JAX-RS resource is implemented as a stateless session bean then the validation is done twice: first on the EJB proxy and on the real implementation. This results in two constraint errors although there is basically just one error.

The interesting part: If you resend the request. Then you get a proper result with just one violation. If you do a valid request and then an invalid you get the two violations again (see also the reproduce section).

I created the issue here because I think it is an integration issue with JAX-RS, bean validation and EJBs.
