   Preondition Violations

   Type org.eclipse.emf.edit.provider.IChangeNotifier of variable changeNotifier does not match with type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable result
   - Make classes org.eclipse.emf.edit.provider.IChangeNotifier and java.util.List extend a common superclass

   Preondition Violations
   Unmatched statement result=new ArrayList<EStructuralFeature>(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
