DDC-1204: Single Table Inheritance - Columns of one hierarchy are dropped

[doctrinebot]

Jira issue originally created by user johannes:

In the following example, the columns of the classes B, C, D are not in the database schema. Only those of the classes A and E.

/****
 * @ORM\Entity
 * @ORM\Table(name = "a")
 * @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="type", type="string", length=20)
 * @ORM\DiscriminatorMap({
 *     "c"   = "C",
 *     "d"   = "D",
 *     "e"   = "E"
 * })
 */
abstract class A { }

/****
 * @ORM\Entity
 */
abstract class B extends A { }

/****
 * @ORM\Entity
 */
class C extends B { }

/****
 * @ORM\Entity
 */
class D extends B { }

/****
 * @ORM\Entity
 */
class E extends A { }

Comment created by johannes:

The problem here is that class B is not part of the discriminator map which was necessary due to issue #DDC-1203. So, once that is resolved this can likely be closed as well.
