It sounds like this is still not the last one but I’m ok with your check since the real GA will be higher and we’re real close.

"On October 6, 2018, distribution of Windows version 1809 (build 17763[18]<https://en.wikipedia.org/wiki/Windows_Server_2019#cite_note-18>) was paused while Microsoft is investigating an issue with user data being deleted during an in-place upgrade.[19]<https://en.wikipedia.org/wiki/Windows_Server_2019#cite_note-19> It affected systems where a user profile folder (e.g. Documents, Music or Pictures) had been moved to another location, but data was left in the original location.[20]<https://en.wikipedia.org/wiki/Windows_Server_2019#cite_note-20>As Windows Server 2019 is based on the Windows version 1809 codebase, it too was removed from distribution.[21]<https://en.wikipedia.org/wiki/Windows_Server_2019#cite_note-21>””

I got the  info that the GA   of  Windows Server 2019 has build number   17763
Should I update the webrev to check this build number (would mean we do
not detect the preview as Windows Server 2019) ,  or keep  it the way it is ?

Current webrev :


Best regards, Matthias

Hello Bob,

Hi Bob,
    no problem ,  we can wait a few  days  until   the final version of Win

2019   is out, and check the buildNumber   again :

seems  Windows server 2019  is GA now :


We don’t usually add logic to the JDK related to unreleased operating


so I think we can process with the review .
Still have to find out the buildNumber of the GA version, probably it has

incremented again .

Bug/webrev :



Thanks, Matthias
