My idea is create BaseTreeEntity

/****
 * @MappedSuperclass 
 */
abstract class BaseTreeEntity
{
    /****
     * @Id
     * @Column(type = "integer")
     * @GeneratedValue
     * @var int
     */
    protected $id;
    /****
     * @ManyToOne(targetEntity="static")
     * @JoinColumn(name="parent_id", referencedColumnName="id")
     * @var BaseTreeEntity|NULL  
     */     
    protected $parent;
}

/****
 * @Entity
 * @property Foo|NULL $parent 
 */ 
class Foo extends BaseTreeEntity {}

/****
 * @Entity
 * @property Bar|NULL $parent 
 */ 
class Bar extends BaseTreeEntity {}

Comment created by @guilhermeblanco:

Since you point to a different instance in each Association of child classes, the association definition cannot be declared in parent class.
If you still want to enforce this, you must define the root hierarchy class as targetEntity.

Marking the ticket as invalid.
