The current Windows OS detection code in os_windows.cpp and  
 in java.base/windows/native/libjava/java_props_md.c  does not recognize Windows Server 2019 (to be released in October 2019).
Windows Server 2019  is currently recognized as "Windows Server 2016" which is put into the os name system property (plus printed in the hs_err file).
A fix is  to add a check for the buildNumber which could be used to  distinguish the versions.

Fix Request: I request the backport of this fix to jdk8u. Windows Server 2019 should be correctly supported. RFR thread: https://mail.openjdk.java.net/pipermail/jdk8u-dev/2019-March/008834.html

Fix Request I would like to get the fix downported to jdk11. Windows Server 2019 is currently recognized as "Windows Server 2016" in jdk11, which is put into the os name system property (plus printed in the hs_err file). Having the wrong System property + output fixed in the LTS release jdk11 would be desired. The patch applies cleanly.

It's been re-released as of today: https://cloudblogs.microsoft.com/windowsserver/2018/11/13/update-on-windows-server-2019-availability/ and still with version 1809. This fix is expected for JDK 12
