   Preondition Violations

   Type org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder of variable eProperties does not match with type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable result
   - Make classes org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder and java.util.List extend a common superclass
