OpenTelemetry's traceId and spanId not logged after RestClient call

[jv-nxtproj]

Describe the bug

OpenTelemetry's traceId and spanId not logged has been fixed recently #26562

However, there is a remaing issue when handling the result of a reactive rest client call

Resource

@Path("/hello")
public class GreetingResource {
   private static final Logger LOG = Logger.getLogger(GreetingResource.class);
   @Inject
   GreetingService service;

   @RestClient
   GreetingClient greetingClient;

   @SneakyThrows
   @GET
   @WithSpan
   @Produces(MediaType.TEXT_PLAIN)
   public CompletableFuture<String> hello() {
      LOG.info("generate uuid");
      String uuid = UUID.randomUUID().toString();
      LOG.info("loop " + uuid);
      return greetingClient.greeting("RESTEasy_Reactive_" + uuid)
            .thenApply(msg -> {
               LOG.info("back "+ msg);
               return msg;
            })
            .toCompletableFuture();
   }

   @GET
   @WithSpan
   @Produces(MediaType.TEXT_PLAIN)
   @Path("/greeting/{name}")
   public String greeting(String name) {
      String res = service.greeting(name);
      LOG.info(res);
      return res;
   }
}

Client

@Path("/hello")
@RegisterRestClient(configKey="greeting-api")
public interface GreetingClient {
   @GET
   @Path("/greeting/{name}")
   CompletionStage<String> greeting(@PathParam("name") String name);
}

Expected behavior

All traces related to one transaction should be logged under same id

Actual behavior

10:51:38 INFO  traceId=acf609ed27927c523adeef15e38c68d8, parentId=9a30b66aed506cc5, spanId=b861b34e21bc9556, sampled=true [co.nx.nx.ba.GreetingResource] (executor-thread-0) generate uuid

10:51:38 INFO  traceId=, parentId=, spanId=, sampled= [co.nx.nx.ba.GreetingResource] (vert.x-eventloop-thread-1) back hello RESTEasy_Reactive_40a7b65c-e5f2-4973-8acd-bf81bea9b72d

Last line (logged inside thenApply) has no traceId

I believe this is a duplicate from RestClient Reactive, MDC lost
@jv-nxtproj do you agree?

@brunobat You're right.
