Jira issue originally created by user johannes:

I have the following class inheritance; if I have the mapped super class in there, the discriminator column is not populated; if I remove it, it is correctly set.

/****
 * @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"
 * })
 */
abstract class A { }

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

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

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

The following hierarchy doesn't work after commit 5ff44b5ec7.

The thrown exception is:
'Entity\AbstractMaschine' has to be part of the descriminator map of 'Entity\Inventory'

Inventory is just a plain abstract class which contains the @Id field and a few methods used by all subclasses.

Yes, please add it to the discriminator map, it is necessary for internal algorithms that this class is in the map.

Ok this has been changed, its not necessary for abstract classes anymore.
