   Preondition Violations

   Type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable childrenFeatures does not match with type org.eclipse.emf.common.ui.DiagnosticComposite.TextProvider of variable textProvider
   - Make classes java.util.List and org.eclipse.emf.common.ui.DiagnosticComposite.TextProvider extend a common superclass

       if (textProvider == null)

   2 | textProvider = new TextProvider();

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

   --- | ---
   1 | Type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable childrenFeatures does not match with type org.eclipse.emf.common.ui.DiagnosticComposite.TextProvider of variable textProvider

   3 | Unmatched return textProvider;

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