ADDITIONAL SYSTEM INFORMATION :

macOS Monterey
openjdk version "17.0.4.1" 2022-08-12
OpenJDK Runtime Environment (build 17.0.4.1+1)
OpenJDK 64-Bit Server VM (build 17.0.4.1+1, mixed mode, sharing)

A DESCRIPTION OF THE PROBLEM :
When building JDK17u with Xcode 14.1, the
awt.Robot's following API causes incorrect pixel color in screen captured BufferedImage.

* java.awt.Robot.createScreenCapture()
* java.awt.Robot.createMultiResolutionScreenCapture()

Screen capture by Robot in JavaFX works correctly.
It can be reproduced on both x86_64 and aarch64.

I note that this report is not a duplicate of JDK-8295779. The recently reported JDK-8296654 is also not a duplicate of JDK-8295779.

The evaluator failed in the build step.
They appear to be ignoring the reproduction steps.

The JDK can be built with the following build options
--disable-warnings-as-errors

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Build with Xcode 14.1
2. Launch a test program
3. Press the screenshot button

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The screenshot image appears in the application without pixel color issues.

ACTUAL -
Pixel color is incorrect.
