Description

Using the following code works fine with Tomee (mvn tomee:run) and return a 201 OK response along with the location.

    @POST
    public void post(@Context UriInfo uriInfo,
                     @Suspended AsyncResponse asyncResponse,
                     @NotNull @Valid MyDTO myDTO) throws ParseException {
       CompletableFuture<MyBean> cf = supplyAsync(() -> doSomething(myDTO), executorService);
        cf
                .thenAccept(myBean -> {
                    URI location = uriInfo.getRequestUri().resolve(uriInfo.getPath() + "/" + myBean.getId());
                    Response response = Response.created(location).build();
                    asyncResponse.resume(response);
                }).exceptionally(e -> {
                    logger.error("An Error occurred.", e);
                    asyncResponse.resume(Response.serverError().build());
                    return null;
                });
    }

But when called in tests with OPENEJB EMBEDDED like this :

        Properties p = new Properties();
        p.setProperty(OpenEjbContainer.OPENEJB_EMBEDDED_REMOTABLE, "true");
        p.setProperty(EJBContainer.APP_NAME, "/app");
        EJBContainer ejbContainer = EJBContainer.createEJBContainer(p);

It fails with this.context being null at (with exceptionnaly not bein called in my method) :
