Symfony 3 Routing for custom reusable Bundle ignored

Question

I'm creating a reusable bundle for my projects which depends heavily on overrides. Weirdly at some point my routing got ignored and I can't get it to work.

Note: AppBundle extends MyBundle

routing.yml

my:
    resource: '@MyBundle/Controller/'
    type: annotation
app:
    resource: '@AppBundle/Controller/'
    type: annotation

src/MyBundle/Controller/IndexController.php

<?php

namespace MyBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

class IndexController extends Controller
{
    /**
     * Index
     *
     * @Route("/", name="index")
     * @Method("GET")
     */
    public function indexAction()
    {
        return $this->render('index.html.twig');
    }

}

composer.json

...
"autoload": {
    "psr-4": {
        "AppBundle\\": "src/AppBundle",
        "MyBundle\\": "src/MyBundle"
    },
    "classmap": [
        "app/AppKernel.php",
        "app/AppCache.php"
    ]
},
...

But I still get a NotFoundHttpException - No route found for "GET /"

Am I missing some special configuration for bundles?

Update: obviously it has something to do with parenting the bundle. When I remove the getParent() function everything works as expected again - however I need this to override the bundle.

namespace AppBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AppBundle extends Bundle
{
    public function getParent()
    {
        return 'MyBundle';
    }

}

Try '../../src/MyBundle/Controller' and '../../src/AppBundle/Controller'

It's known issue , but " bundle inheritance is now deprecated and will be removed in Symfony 4 ".
