   Preondition Violations

   Type org.eclipse.emf.importer.ModelImporter of variable modelImporter does not match with type java.util.List<org.eclipse.emf.ecore.util.FeatureMap.Entry> of variable removals
   - Make classes org.eclipse.emf.importer.ModelImporter and java.util.List extend a common superclass

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

   8 | removals = new BasicEList<Entry>();

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

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