*Hi Rick, *
*OpenJDK 17 Early Access build 18****is now available at
**https://jdk.java.net/17 <https://jdk.java.net/17>*
* These early-access , open-source builds are provided under the
o GNU General Public License, version 2, with the Classpath
Exception <https://openjdk.java.net/legal/gplv2+ce.html>
* Release Notes are available at http://jdk.java.net/17/release-notes
<https://jdk.java.net/17/release-notes>
**G1 pauses may be extremely long with EA build JDK-17+18*
*During performance testing we noticed that due to a recent change
(JDK-8262068) GC pauses after a G1 full GC may be extremely slow. The
problem has been fixed with JDK-8264987 and that has already been
integrated. This change will be available with the following EA build
JDK-17+19. For more technical info please see [1]
*JEP 382 [2]** - Starting with build 19, **JDK 17 for macOS is
*temporarily* switched from using OpenGL**to using Apple's Metal
API**for Java 2D rendering.*
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.
Rgds,Rory
