   Preondition Violations

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