title: TZupdater failing with tzdata2016g release
body: <p>TZUpdater 2.1.0 is failing with tzdata2016g release. For Java 8 it fails with "Source directory does not contain file: VERSION" error, while it completes with "JRE updated to version : tzdataunknown" comment for Java 7. </p>
  
  <p>The reason of this seems to be recent change of IANA tzdata distribution: Unsetting VERSION field of Makefile. There is a bug reported regarding the issue: <a href="https://bugs.openjdk.java.net/browse/JDK-8166928">https://bugs.openjdk.java.net/browse/JDK-8166928</a>.</p>
  
  <p>DST date(30th October 2016) is getting closer and we at least need a workaround for this. Is it, somehow, possible?</p>
