The ongoing support and updates for “older” versions of Java (including 9 & 10) has changed since the introduction of the six-monthly release cycle.

You can download Oracle’s OpenJDK 11 build, or builds from the community led AdoptOpenJDK.

As of Java 11, OpenJDK has feature parity with Oracle’s JDK, so if you want to use a free JDK, use OpenJDK.

If you want to receive updates to Java 8, you may need to pay Oracle or to find another JDK build.

Oracle’s JDK 8 will no longer receive public updates after January 2019.

You can still download the commerical Oracle JDK for free and use it for free in development/test environments.

This summary is something I wrote in September’s Annotated Monthly, updated to reflect the release of Java 11: If you don’t want to use either of the Oracle JDK builds (for example if their support or updates policies doesn’t suit you), investigate what Azul, IBM, Red Hat, and the community-led AdoptOpenJDK have to offer instead.

Stephen Colebourne has written a post summarizing the different JDK builds from the different vendors, and explaining how (and why) all these vendors provide different builds based off the same code (i.e. Some of these other vendors, for example, may continue to provide updates and/or support for Java 9 (which Oracle will not). For years, we’ve been used to using their JDK for free and so it has generally been our default, but there are other vendors who provide JDKs, and they have different support models (free and paid for), and different attitudes towards providing updates for different versions of Java. Having said that, Oracle is not the only vendor in this game.

So, if you’re using Oracle’s OpenJDK build, you should be prepared to update to each new version of Java as it comes out (or run an older version that won’t get updates). What this means is now Java 11 is out Oracle will no longer be updating their OpenJDK builds for 10 or 9. If you’re using Oracle’s OpenJDK build, Oracle won’t be providing updates to past versions. There’s an important difference between these two builds though – if you’re using Oracle’s commercial JDK, you’ll get updates and support. Note that since Java 11, Oracle’s commercial JDK and Oracle’s OpenJDK builds are functionally the same, so we should be able to run our applications on either without having to make any changes or losing any features.

Oracle’s OpenJDK (open source) – you can use this for free in any environment, like any open source library.

Oracle’s JDK (commercial) – you can use this in development and testing for free, but if you use it in production you have to pay for it.

with paid support) or for free (which many of us were doing), they now have two different JDK builds:

From Java 11, Oracle has changed the license of their JDK, so instead of having a single JDK build which can be used either commercially (i.e. In the past, many of us simply downloaded Oracle’s JDK and used this in development, in testing, and in production. This warning is on the download page for Oracle’s commercial JDK – don’t ignore it! Changes to the Oracle JDK triage and bug reports) they expect for their version

Azul, IBM, Oracle, Red Hat, or other OpenJDK build) The new six-monthly release cadence and Oracle’s changes in licensing and support model mean that any organization that deploys a Java application should take this opportunity to look at: This topic is quite a complex one since there are a number of overlapping changes that have come together since the release of Java 8. Some news is even suggesting that we now have to pay to use Java – this is not true! If you stay up to date on news from the Java community, you may have heard that Oracle have changed their support model for Java.
