Re: [resteasy-dev] resteasy jax-rs fail fast on entity validation exception

if ((violationsContainer.isFieldsValidated()

result = invokedMethod.invoke(resource, args);

I've reviewed the code. I do not find that a method with a validation error is called. The validation error is thrown. It is captured[1] and returned to the caller in the Response object as an HTTP 400 error.[2] [1]https://github.com/resteasy/Resteasy/blob/master/resteasy-jaxrs/src/mai...

I have been investigating some unexpected behaviour in how entity validations exceptions are propagated through WF/EAP when http post requests are made via rest endpoints. One thing I have noticed in the resteasy-jaxrs module is that in org.jboss.resteasy.core.MethodInjectorImpl.invoke() the method parameters are validated [1], but the method is still invoked, irrespective of the outcome of the call to the validator [2] Is there is a possibility of failing a method invocation after the validation call [1], so that we do not invoke the method, which ends up failing anyway due to validation exceptions?
