Calling getNativeScaleFactor(NULL) leads that
"com.ubuntu.user-interface" "scale-factor" and
"com.canonical.Unity.Interface" "text-scale-factor" properties are just
skipped in getDesktopScale(char *output_name) method from systemScale.c
file. Should there be provided some default output screen name?
I am not sure that the fix can be pushed to the jdk9/dev repository. The
usual practice is to always push it to the jdk9/client first.
Thanks,
Alexandr.

But I'm fine with any list, as long as the change gets reviewed :)

Hi,
can I please have a review for the following trivial fix:
http://cr.openjdk.java.net/~simonis/webrevs/2016/8163408/
https://bugs.openjdk.java.net/browse/JDK-8163408
I'd like to push this directly to jdk9/dev if possible because the
problem has already spread across all the other repos and I'd like to
fix it as fast as possible in all repos.
The fix for "8149115: [hidpi] Linux: display-wise scaling factor
should probably be taken into account" changed the prototype for
getNativeScaleFactor() in systemScale.h from:
int getNativeScaleFactor();
to
double getNativeScaleFactor();
But forgot to add the "char*" parameter to the signature which is
required by the implementation in systemScale.c (and the various call
sites):
double getNativeScaleFactor(char *output_name) {
This leads to the following waring/error:

I observed these warnings/errors with 4.8.5 and it is a miracle for me
why newer versions of GCC (apparently 4.9.2 which seems to be Oracles
officially supported compiler according to
https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms)
or gcc 5.4.0 whiohc I've tried on Ubuntu 16.04 don't detect this
problem?
Thank you and best regards,
Volker
