      Description

      Situation:
      Create an abstract base class (@InheritanceType("JOINED")) and a derived class, both having the annotation @HasLifecycleCallbacks and both having a method with annotation @PostLoad (different method names). The sequence of methods being called when an object is loaded from the database is not as expected.

      Expected output:
      Called Che\Tmp\BaseClass::PostLoadBase
      Called Che\Tmp\DerivedClass::PostLoadDerived
      (base value, derived value)

      Actual output:
      Called Che\Tmp\BaseClass::PostLoadBase
      Called Che\Tmp\DerivedClass::PostLoadDerived
      Called Che\Tmp\BaseClass::PostLoadBase
      (base value)

      Test code:
      See attachment for classes

      // Assume there is an entity manager $em
      // Create object
      $newDerived = new \Che\Tmp\DerivedClass();
      $em->persist($newDerived);

      // Fetch object
      $derived = $em->findById('\Che\Tmp\DerivedClass', 1);
      $derived->echoList();

      Possible problem cause

      ClassMetadataInfo::addLifecycleCallback($callback, $event) method has a note 'If the same callback is registered more than once, the old one will be overridden'. We are not sure whether this is the case.
