   Preondition Violations
   Unmatched statement childrenFeatures.add(ChangePackage.Literals.EOBJECT_TO_CHANGES_MAP_ENTRY__VALUE); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   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

   5 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero
