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

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
