@wangrenlei The Travis result looks fine. Builds using default or US locale
passed:

There're tests that fail with other Locales as reported by
[NIFI-3466](https://issues.apache.org/jira/browse/NIFI-3466). So for this PR, I
think it's time for further detailed code level review. I am not sure if I have
enough bandwidth to review it this week but try when I have time.
Anyone interested in this contribution, please jump in reviewing process!
Thanks!
