### Question:
MessageScrubber { @VisibleForTesting static boolean bug1162183Affected(Map<String, String> attributes) { final ImmutableSet<String> affectedDocumentTypes = ImmutableSet.of("first-shutdown", "main", "saved-session"); return ParseUri.TELEMETRY.equals(attributes.get(Attribute.DOCUMENT_NAMESPACE)) && affectedDocumentTypes.contains(attributes.get(Attribute.DOCUMENT_TYPE)) && attributes.get(Attribute.APP_VERSION) != null && attributes.get(Attribute.APP_VERSION).matches("^([0-3][0-9]|4[0-1])\\..*"); }  static void scrub(Map<String, String> attributes, ObjectNode json);  }### Answer:
