Hello,
Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8151333
webrev: http://cr.openjdk.java.net/~ssadetsky/8151333/webrev.00/
This just suppose to be a potential issue. It is discovered by
AddressSanitizer.
When Xinerama is used the number of screens that is seen by WM is always
1. But X11GraphicsDevice#getDisplayMode() may be called with the "real"
screen number and this is not checked in the native code and thus may
cause incorrect memory addressing.
As a solution a check for validity of the screen number is added.
Test would require writing native code, so noreg-hard label is added.
