Jira issue originally created by user thinkscape:

Subclasses that override parent class properties and define relations will not work as expected, because AnnotationDriver/Reader will only use the parent class annotation (discarding whatever subclass defined).

The following code will produce error:

[Mapping]  FAIL - The entity-class 'Test\Office' mapping is invalid:
* The mappings Test\Office#employees and Employee#office are incosistent with each other.

Test code:

<?php
namespace Test;

use Doctrine\ORM\Mapping as ORM;

/****
 * @ORM\Entity
 */
class Office 
{
    /****
     * @ORM\OneToMany(targetEntity="Person", mappedBy="office")
     * @var Person[]|ArrayCollection
     */
    protected $people;

    /****
     * @ORM\OneToMany(targetEntity="Employee", mappedBy="office")
     * @var Employee[]|ArrayCollection
     */
    protected $employees;

}

/****
 * @ORM\Entity
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="type", type="string")
 * @ORM\DiscriminatorMap({"employee" = "Employee"})
 */
class Person
{
    /****
     * @ORM\ManyToOne(targetEntity="Office", inversedBy="people")
     * @var Office
     */
    protected $office;
}

/****
 * @ORM\Entity
 */
class Employee extends Person
{
    /****
     * @ORM\ManyToOne(targetEntity="Office", inversedBy="employees")
     * @var Office
     */
    protected $office;
}

Ok, I get that it's not supported right now, but why did you mark it as resolved?
