      I have following JAX-RS resource (see attached file):

      
@Path("test")
@ApplicationPath("rest")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class DemoApplication extends Application {

    public record Data(String data) {}

    @GET
    @Path("short-record-response")
    public Response shortRecordR() {
        return Response.ok().entity(new Data("ok")).build();
    }

    @GET
    @Path("short-record")
    public Data shortRecord() {
        return new Data("ok");
    }
}

      I get a correct response with 8.0.0.Beta:

      $ curl -X GET -H 'Accept: */*' -i 'http://localhost:8080/gezip-demo-1.0-SNAPSHOT/rest/test/short-record' 
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: application/json
Content-Length: 13

{"data":"ok"}

$ curl -X GET -H 'Accept: */*' -i 'http://localhost:8080/gezip-demo-1.0-SNAPSHOT/rest/test/short-record-response' 
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: application/json

{"data":"ok"}

      However, serialization fails on 8.0.0.GA.CR2 and CR1:

      $ curl -X GET -H 'Accept: */*' -i 'http://localhost:8080/gezip-demo-1.0-SNAPSHOT/rest/test/short-record-response' 
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: application/json

{}

$ curl -X GET -H 'Accept: */*' -i 'http://localhost:8080/gezip-demo-1.0-SNAPSHOT/rest/test/short-record' 
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: application/json
Content-Length: 2

{}

      If I define simple container class for a string (with getter and setter) - see the attachment, it gets serialized correctly.
