### Question:
DataUtils implements Serializable { public static List<String> parseStringList(Object object) { if (object == null) { return null; } return Splitter.onPattern("(?:\r?\n)+") .splitToList(object.toString()) .stream() .map(String::trim) .filter(s -> !s.isEmpty()) .collect(Collectors.toList()); }  static Integer tryParseInteger(Object object); static Long tryParseLong(Object object); static List<String> parseStringList(Object object); static String formatInUTC(DateTime date); static DateTime parseFromUTC(String date);  }### Answer:
@Test public void normalizerSplitter() { assertEquals(Lists.newArrayList("\\?.*$-->>", "a-->>b"), DataUtils.parseStringList("\\?.*$-->>\na-->>b\r\r\n\n")); }
