our regular meeting...

> Greetings!
>
> JDK 18 has been released (General Availability) on March 22nd as planned, the
> release cadence is working like clockwork! As a small token of gratitude,
> some of you have been specifically acknowledged in the "The Arrival of Java
> 18" announcement [1]. On behalf of the entire team, let me extend our thanks
> to all of you.

> With JDK 18 released, the focus should now be on making sure your project(s)
> compile and work on JDK 19. As always, if you face any issue with
> early-access builds of JDK 19 please let us know. To help you in this task,
> we have just released a GitHub action to install the OpenJDK Early-Access
> builds. For more information, please check the heads-up below.
>
> I'll conclude with a short teaser, i.e. JavaOne is Back! [2] Stay tuned for
> more details.

> ## Heads-Up: oracle-actions/setup-java
>
> To help you test your project(s), we have released a GitHub Action [3] to
> download and install various JDK builds produced by Oracle. In addition to
> the latest OpenJDK GA builds (GPL v2 W/CPE) and the Oracle JDK builds (NFTC
> license), this action can also download and install OpenJDK early-access
> builds, and early-access builds of OpenJDK projects (ex. Project Loom,
> Project Valhalla, etc.).
>
> When doing tests using EA builds, it is key to always use the upstream EA
> builds from jdk.java.net as issues should be logged against those upstream
> builds, and ideally against a specific build version. This GitHub action is
> actively following the OpenJDK EA builds releases. Please make sure to check
> the announcement [4] for more details, and short FAQ.
>
> To help you isolate regression between different EA builds, we are working to
> add support for archived builds. If you have feedback, please either issue
> the Issue tracker [5] or just send me a mail.
