// Code snippet to read a json file within a class which the method is static  

try {
  InputStream resource = new ClassPathResource("paths.json").getInputStream();

  final ObjectMapper mapper = new ObjectMapper();
  final List<Path> pathsNotFound = new ArrayList<>();
  MappingIterator<List<Path>> iterator = mapper.readValues(mapper.createParser(resource), new TypeReference<List<Path>>() {
                                                           });
  while (iterator.hasNext()) {
    List<Path> paths = iterator.next();
    for (Path path : paths) {
      AclResourceDetails details = permissions.getResource(path.getName());
      if (details == null) {
        pathsNotFound.add(path);
      }
    }
    log.info(pathsNotFound);
  }
} catch (final IOException e) {
  log.error(e);
