      1. Create a rest endpoint with method parameter validation and annotate as an ejb managed bean

      @Stateless
      @Path("/foo")
      public class FooRest {
      ...
      @POST
      @Path("/bar")
      @Consumes(MediaType.APPLICATION_JSON)
      public void addBar(@Valid Bar bar) throws Exception {

      2. Deploy the rest endpoint in a JEE application server
      3. Call the /foo/bar endpoint with an invalid Bar object, the http response code should be 400
      4. Make subsequent calls the to /foo/bar endpoint, the http response code will be 500 until the application is redeployed/ app server restarted

    Description

      In a CDI context; when a rest endpoint has parameter validation defined and is also defined as an ejb managed bean, only the first invocation of the endpoint will call the validation code path for validating the rest method parameters. Subsequent calls to the endpoint will not be validated by resteasy/CDI and will only be validated by the CDI context, which may not handle any ConstraintValidationExceptions correctly. In Wildlfly/EAP this manifests itself with the rest endpoint correctly returning a HTTP 400 (Bad Request) status on the first invocation, but subsequent invocations return a HTTP 500 (Internal Server Error) status.

          Bug - A problem that impairs or prevents the functions of the product. RESTEASY-1296 Field constraints are not validated if resource is an EJB

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
