Hi Magnus,

I haven't found a way to suppress this warning. I tried. There's no way to suppress warnings from mt.exe [1] unfortunately.

We're using Visual Studio 2013 to build JDK, the element was added in 2016. Newer versions of Windows SDK should recognise the element.

Yes, it works as intended. It's recognised by Windows 10 v1703 and later and changes High DPI mode. Other versions of Windows are not affected.

I should've included build-dev into the review process as it affects build system. Can the output of mt.exe be redirected? If it's successful, then its output gets ignored.

Hi Alexey,

Since this patch, I'm getting lots of warnings on Windows:

c:/cygwin64/home/magnusi/hg/sandbox/open/src/java.base/windows/native/launcher/java.manifest : manifest authoring warning 81010002: Unrecognized Element "dpiAwareness" in namespace "http://schemas.microsoft.com/SMI/2016/WindowsSettings";.

Seems this element is not universally recognized. Does it even work as intended?

Do you have any suggestion on how to address this issue?

Could you please review the fix for jdk11?

webrev: http://cr.openjdk.java.net/~aivanov/8199627/webrev.0/

Windows 10 v1703 provides improved High DPI mode: Per-Monitor v2. [1]


When building, manifest tool generates warning for unknown <dpiAwareness> element in manifest. It is because an older Windows SDK is used to build JDK which does not know about an element that was added later. The build succeeds despite the warning.

Thank you in advance.
