The new name is Oracle GraalVM, and along with the new name is a new license model: You can now use all the goodness in Oracle GraalVM for free. That’s both for development and production, by the way.
Here are some of the key details.
Oracle is making Oracle GraalVM for JDK 17, Oracle GraalVM for JDK 20 (previously known as Oracle GraalVM Enterprise), and subsequent releases, including all quarterly security updates, free.
These releases will be available under the GraalVM Free Terms and Conditions (GFTC) license. This license, subject to its conditions, permits free use for all users, even for production use. Redistribution is permitted if it is not for a fee.
For designated Long-Term Support (LTS) releases such as GraalVM for JDK 17, Oracle will provide free GFTC releases until one full year after the subsequent LTS release. Prior releases are not affected by this change.
You can now easily download, use, share, and redistribute Oracle GraalVM without needing a click-through license agreement. And Oracle will continue to provide GPL-licensed GraalVM Community Edition releases under the same terms as Oracle builds of OpenJDK.
Oracle GraalVM downloads are available on the Java Downloads page. To get started, consult the installation guides, documentation, and release notes for Oracle GraalVM for JDK 17 and Oracle GraalVM for JDK 20.
Take care,

Handling time zones in distributed systems, Part 1
Handling dates and times in applications is a common and challenging problem requiring a particular design and implementation to ensure a correct solution. Mohamed Taman starts his two-parter by exploring the issue and presenting a sample application implementation, with an API, to provide an end-to-end solution for a distributed environment.
Handling time zones in distributed systems, Part 2
Building on the first article in this series, Mohamed Taman shows how to use JSR 310, the java.time API, to implement zoned date and time operations into an end-to-end service. The service uses RESTful-based controllers to connect to business logic that resides in the services layer, while connecting to a database through the repository layer.
Method handles: A better way to do Java reflection
What is reflection? Why does it matter? The previous articles in Ben Evans’ three-part series explored the topic and discussed the implementation of reflection as it shipped in versions of Java up to and including Java 17. This series concludes by building upon this base and explaining the new implementation that ships with Java 18 and later. |
