Hello, please review change 8211106 . It updates the Windows OS detection code to recognize Windows Server 2019 .
For this we have to look at the build number (dwBuildNumber of OSVERSIONINFOEX), https://docs.microsoft.com/en-us/windows/desktop/api/Winnt/ns-winnt-_osversioninfoexa because dwMajorVersion and dwMinorVersion are the same for Windows server 2016 and 2019 . The build number used to compare ( 17677 ) is for Windows Server 2019 preview , most likely the final version will have a higher build number but this is fine for the coding . Bug/webrev : https://bugs.openjdk.java.net/browse/JDK-8211106 http://cr.openjdk.java.net/~mbaesken/webrevs/8211106.0/webrev/ Thanks, Matthias
