DDC-3303: @ORM\Embedded does not work with extending classes

[doctrinebot]

Jira issue originally created by user TheBelgarion:

I update my symfony 2.5 with ORM 2.5. to try out the Embedded function.
I currently does not work correctly with extending class

/****
 * @ORM\Entity
 * @ORM\Table(name="A", uniqueConstraints={@UniqueConstraint(name="id", columns={"id"})})
 */
class A extends B {}

abstract class Item {

    /****
     * @var $bonus
     * @ORM\Embedded(class="Bonus")
     *
     */
    private $bonus;
}

it only works if i put the definition of the Embedded properties directly in class A ( but it works with all normal properties defined in the Abstract )

Comment created by jpi:

Hi, I confirm this bug.
Im using Symfony 2.7.5 DBAL 2.5.2 ORM 2.5.1.

Error : Property xxx::$description does not exist

Setting the parent class properties to "protected" (instead of private") works and could be an acceptable workaround for some.
