Prestashop: Final Class Lang generate Compile Error for the Proxy Doctrine Class

[Fabuloops]

Describe the bug

Why using a FINAL class on the PrestaShopBundle\Entity\Lang class ?

When i get an attribute group name with doctrine i see this exception :

Compile Error: Class Proxies\__CG__\PrestaShopBundle\Entity\Lang may not inherit from final class (PrestaShopBundle\Entity\Lang)

The doctrine proxy classes use the inheritance of entity class

To Reproduce

        $em = $this->getDoctrine()->getManager();
        $groups = $em->getRepository(AttributeGroup::class)->findAll();
        var_dump($groups[0]->getAttributeGroupLangs()->first()->getPublicname());

Additional information
PrestaShop version: 1.7.6.1
PHP version: 7.1
