Buggy source:

  if (countries != null && !countries.isEmpty()) {
    if (countries.contains(country)) {
      return ParsedField.success(ParsedLocation.newBuilder().country(country).latLng(latLng).build());

Fixed version (ground truth):
private ParsedField<ParsedLocation> applyMatchWithCountry(){
  List<Country> countries=getCountriesFromCoordinates(latLng);
  if (countries != null && !countries.isEmpty()) {
    if (countries.contains(country)) {
      return ParsedField.success(ParsedLocation.newBuilder().country(country).latLng(latLng).build());
    }
    Optional<Country> equivalentMatch=containsAnyCountry(CountryMaps.equivalent(country),countries);
    if (equivalentMatch.isPresent()) {
      return ParsedField.success(ParsedLocation.newBuilder().country(equivalentMatch.get()).latLng(latLng).build());
    }
    Optional<Country> confusedMatch=containsAnyCountry(CountryMaps.confused(country),countries);
    if (confusedMatch.isPresent()) {
      return ParsedField.success(ParsedLocation.newBuilder().country(confusedMatch.get()).latLng(latLng).build(),Collections.singletonList(new InterpretationIssue(IssueType.COUNTRY_DERIVED_FROM_COORDINATES,DwcTerm.country)));
    }
  }
  LOG.info("String_Node_Str",latLng);
  for (  CoordinatesFunction transformation : alternativeTransformations) {
    LatLng latLngTransformed=transformation.getTransformer().apply(latLng);
    List<Country> countriesFound=getCountriesFromCoordinates(latLngTransformed);

      continue;
    }
    if (countriesFound.contains(country)) {
      List<InterpretationIssue> issues=new ArrayList<>();
      CoordinatesFunction.getIssueTypes(transformation).forEach(issueType -> issues.add(new InterpretationIssue(issueType,getCountryAndCoordinatesTerms())));
