Jira issue originally created by user naroga:

When using a return typehint on the entity getter/setter, the proxies are not generated with the typehint, which throws an error when called.

Example:

/****
 * @ORM\Table(name="carro_marca")
 * @ORM\Entity
 */
class Marca
{
    /****
     * @ORM\Column(name="marca_id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="NONE")
     */
    private $id;

    /****
     * @return integer
     */
    public function getId() : \int
    {
        return $this->id;
    }
}

Creates the following getId on the Proxy:

class Marca extends \AppBundle\Entity\Carro\Marca implements \Doctrine\ORM\Proxy\Proxy
    {
        ...
        /****
         * {@inheritDoc}
         */
        public function getId()
        {
            ...
        }
}

Which makes my application throw the following error:

{quote}
Compile Error: Declaration of Proxies*CG*\AppBundle\Entity\Carro\Marca::getId() must be compatible with AppBundle\Entity\Carro\Marca::getId(): int
{quote}
