bug in generate entities with many2many relationships from xml/yml shcemes

I try use many2many relations in my symfony2 learning project https://github.com/symfony/symfony.git
But entities thar generates from yml schemes did not meet entities from doctrine2 guide or entities from beberlei Whitewashing project https://github.com/beberlei/Whitewashing/tree/master/Blog

After that I try generate similar entitries is doctrine2-sandbox. Problem is the same
I attached yml schemes and result entities.

Problem:

• Entities\Address does not have relations with Entities\User
• In Entities\User property $adresses instance of Entity\Address. But this Doctrine\Common\Collections\ArrayCollection or no?

      /**
       * @var Entity\Address
       */
      private $addresses;

• In Entities\User not at __constructor() method:

      public function __construct()
      {
          $this->addresses = new ArrayCollection();
      }
