   Preondition Violations

   Type org.eclipse.emf.edit.provider.IChangeNotifier of variable changeNotifier does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes org.eclipse.emf.edit.provider.IChangeNotifier and org.eclipse.core.resources.ResourceAttributes extend a common superclass

   Preondition Violations
   Unmatched statement changeNotifier=new ChangeNotifier(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   Preondition Violations
   Unmatched statement resourceAttributes=resource.getResourceAttributes(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
