ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
When I did a System.getProperty("os.name"), it returns "Windows 8.1" and System..getProperty("os.version"), "6.3" is returned. My OS is Windows 10, so System.getPropery("os.name") should return "Windows 10" and System.getProperty("os.version") "10.0". This is not really a bug, but need to be fixed.

REGRESSION.  Last worked in version 7u75
