Add support for Windows 2016

A DESCRIPTION OF THE REQUEST :
FULL PRODUCT VERSION :
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) Client VM (build 25.77-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
OS Name: Microsoft Windows Server 2016
OS Version: 10.0.14300 N/A Build 14300

A DESCRIPTION OF THE PROBLEM :
When I execute a System.getProperty("os.name"), it returns "Windows NT (unknown)" and System..getProperty("os.version"), "10.0" is returned. My OS is Windows server 2016, so System.getPropery("os.name") should return "Windows server 2016". This is not really a bug, but need to be fixed.


JUSTIFICATION :
Below java api calls are not giving Windows server 2016 OS details.
This OS support needs to added to show proper OS details.

System.getProperty("os.name");
System.getProperty("os.version");

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
My OS is Windows server 2016, So System.getPropery("os.name") should return "Windows server 2016".
ACTUAL -
When I execute a System.getProperty("os.name"), it returns "Windows NT (unknown)" and System.getProperty("os.version"), "10.0" is returned.
