   Preondition Violations

   Type org.eclipse.emf.importer.ModelImporter of variable modelImporter does not match with type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.EObject> of variable eCrossReferences
   - Make classes org.eclipse.emf.importer.ModelImporter and org.eclipse.emf.common.util.EList extend a common superclass

   Preondition Violations
