   Preondition Violations

   Type java.util.List<org.eclipse.emf.ecore.util.FeatureMap.Entry> of variable removals does not match with type org.eclipse.emf.ecore.resource.URIConverter.WriteableOutputStream.Buffer of variable buffer
   - Make classes java.util.List and org.eclipse.emf.ecore.resource.URIConverter.WriteableOutputStream.Buffer extend a common superclass

   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
