quarkus with a vertx session handler

[tomschulze]

I am trying to migrate a Vert.x application to Quarkus. I need to add middleware handlers to my router. In the case below I want to add a session handler. I don't understand why it does not work. When I access the route "/", Quarkus throws a NullPointerException because rc.session() is not intialized. What am I missing here?

package me.tom.testapp;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.event.Observes;

import io.quarkus.vertx.web.Route;
import io.vertx.core.Vertx;
import io.vertx.ext.web.Router;
import io.vertx.ext.web.RoutingContext;
import io.vertx.ext.web.handler.SessionHandler;
import io.vertx.ext.web.sstore.LocalSessionStore;

@ApplicationScoped
public class Routes {
  public void init(@Observes Router router, Vertx vertx) {
    router
      .route()
      .handler(SessionHandler.create(LocalSessionStore.create(vertx)));
  }

  @Route(path = "/")
  public void helloWorld(RoutingContext rc) { 
    rc.session().put("test", "test");
    rc.response().end("hello");
  }

  @Route(path = "/test")
  public void yoyo(RoutingContext rc) {
    String test = rc.session().get("test");
    rc.response().end(test);
  }
}

That is the route

 RouteImpl@1159652643{state=RouteState{metadata=null
 path='null'
 name=null
 order=4
 enabled=true
 methods=null
 consumes=null
 emptyBodyPermittedWithConsumes=false
 produces=null
 contextHandlers=[io.vertx.ext.web.handler.impl.SessionHandlerImpl@8713cd2]
 failureHandlers=null
 added=true
 pattern=null
 groups=null
 useNormalizedPath=true
 namedGroupsInRegex=null
 virtualHostPattern=null
 pathEndsWithSlash=false
 exclusive=false
 exactPath=true}}]

The culprit is the route order. Changing the code to

    router
      .route()
      .order(0)
      .handler(SessionHandler.create(LocalSessionStore.create(vertx)));

works. Prior to the change helloWorld() was executed first.
