   Preondition Violations

   Type java.util.Map<java.lang.String,org.eclipse.emf.importer.ecore.EcoreImporterApplication.PackageInfo> of variable nameToPackageInfo does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes java.util.Map and org.eclipse.core.resources.ResourceAttributes extend a common superclass

   Preondition Violations
   Unmatched statement nameToPackageInfo=new HashMap<String,PackageInfo>(); 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

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