Exception thrown during respond() is not handled with url mapping for 500

[kuceram]

Having a converter for Domain class which might throw an exception, i.e.:

class MyDomainMarshaller {

    @javax.annotation.PostConstruct
    void registerMarshallers() {
        JSON.registerObjectMarshaller(MyDomain) { myDomain ->
            throw new RuntimeException("some exception")
        }
    }
}

brings problem when rendering response with controller respond method:

def show(Long id) {
    respond MyDomain.get(id)
}

This exception should result in rendering 500 defined in url mappings:

"500"(controller: "error", action: "index")

It renders 200 with following content [. It seems that response was partially rendered.

With interceptors seem to have the same problem. At least 404 are not mapped.

Yeah the issue here is the response has already been committed by the time the exception happens so at that point there is no going back
