Symfony2白屏app.php：ProxyFactory.php

Question

I've got a white screen in app.php but not in app_dev.php On Apache logs :

PHP Fatal error: require(): Failed opening required '[...]app/cache/prod/doctrine/orm/Proxies\_CG_SdzForumBundleEntityCategory.php' (include_path='.;C:\php\pear') in [...]\vendor\doctrine\orm\lib\Doctrine\ORM\Proxy\ProxyFactory.php on line 92

I already tried:

• cache:clear --env=prod
• cache:clear --env=prod --no-warmup
• cache:warmup --env=prod
• composer.phar update
• chmod 777 -R app/cache app/logs web/js web/bundles web/css
• doctrine:schema:update --force

The problem begin when I tried to move a vendor bundle into my sources because it is not updated by developpers: https://github.com/Herzult/HerzultForumBundle

I think there is many ways to get informations from database, and this forum bundle uses one way that I do not master.

Here are some code

config.yml

doctrine:
    orm:
        auto_mapping: true
        auto_generate_proxy_classes: "%kernel.debug%"
        proxy_namespace: Proxies
        proxy_dir: %kernel.cache_dir%/doctrine/orm/Proxies
        default_entity_manager: default
        metadata_cache_driver: array
        query_cache_driver: array
        result_cache_driver: array

Entity/Category.php

namespace Sdz\ForumBundle\Entity;

use Sdz\ForumBundle\Model\Category as BaseCategory;
use Doctrine\ORM\Mapping as ORM;

/**
 *
 * @ORM\Table(name="sdz_forum_category")
 * @ORM\Entity(repositoryClass="Sdz\ForumBundle\Entity\CategoryRepository")
 */
class Category extends BaseCategory
{

Entity/CategoryRepository.php

namespace Sdz\ForumBundle\Entity;

use Sdz\ForumBundle\Model\CategoryRepositoryInterface;
use Sdz\ForumBundle\Entity\ObjectRepository;

class CategoryRepository extends ObjectRepository implements CategoryRepositoryInterface

//Problem line
