Heads up to anyone who is testing JDK 17 for running apps on macOS. 
Starting with build 19, JDK 17 for macOS is *temporarily* switched 
from using OpenGL to using Apple's Metal API for Java 2D rendering.


If you are running any kind of 2D / Swing/ AWT UI application on 
macOS, and see any rendering related problems
starting with JDK 17 b19, please do report them to us along with a 
test case and screen shots.


You may also set "-Dsun.java2d.opengl=true" to re-enable OpenGL - 
which  implicitly disables Metal - to confirm that it is a Metal 
related rendering glltch.
