This is an announcement that openjdk-17 is now in the repos. You can update your environmental variables to use this for your applications like so:
java --version should report that you are using Java 17. Currently the version in stable is 17.0.2 however 17.0.3 should be in the next sync.
Many applications in the repo have already been updated to use openjdk-17 (in fact you may have already had openjdk-17 get installed to your system if you have a java-based application installed) and the remaining ones are being worked on. Once we finish determining if all applications can be updated to use openjdk-17 or if they need to remain on an older version expect that we will update maven/gradle/etc so that they use openjdk-17 by default. This may be a breaking change for you however you can always override the JDK to use by appropriately setting the JAVA_HOME and PATH variables.
