'SimpleDateFormat' without locale

Reports instantiations of java.util.SimpleDateFormat or java.time.format.DateTimeFormatter that do not specify a java.util.Locale. These calls will use the platform default locale, which depends on the OS settings. This can lead to surprising behaviour when the code is run on a different platform or the OS settings are changed.

Example:

  new SimpleDateFormat("yyyy");
  DateTimeFormatter.ofPattern("d/M/y");
