Making open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.
Chapter 1. Support policy
Red Hat will support select major versions of Red Hat build of OpenJDK in its products. For consistency, these are the same versions that Oracle designates as long-term support (LTS) for the Oracle JDK.
A major version of Red Hat build of OpenJDK will be supported for a minimum of six years from the time that version is first introduced. For more information, see the OpenJDK Life Cycle and Support Policy.
RHEL 6 reached the end of life in November 2020. Because of this, Red Hat build of OpenJDK is not supporting RHEL 6 as a supported configuration.
Chapter 2. Eclipse Temurin overview
Eclipse Temurin is a free and open source implementation of the Java Platform, Standard Edition (Java SE) from the Eclipse Temurin Working Group. Eclipse Temurin is based on the upstream Red Hat build of OpenJDK 8u, Red Hat build of OpenJDK 11u, and Red Hat build of OpenJDK 17u projects and includes the Shenandoah Garbage Collector from version 11 and later versions.
Eclipse Temurin does not vary structurally from the upstream distribution of Red Hat build of OpenJDK. Eclipse Temurin shares the following similar capabilities as Red Hat build of OpenJDK:
- Multi-platform - Red Hat offers support of Eclipse Temurin on Microsoft Windows, RHEL and macOS, so that you can standardize on a single Java platform on numerous environments, such as desktop, data center, and hybrid cloud.
- Frequent releases - Eclipse Temurin delivers quarterly updates of JRE and JDK for the Red Hat build of OpenJDK 8, Red Hat build of OpenJDK 11, and Red Hat build of OpenJDK 17 distributions. These updates are available as RPM, MSI, archive files, and containers.
- Long-term support (LTS) - Red Hat supports the recently released Eclipse Temurin 8, Eclipse Temurin 11, and Eclipse Temurin 17. For more information about the support lifecycle, see Red Hat build of OpenJDK Life Cycle and Support Policy.
Chapter 3. Downloading Eclipse Temurin distributions
You can download Eclipse Temurin distribution from numerous sources, such as the Eclipse Adoptium website.
Both the Eclipse Adoptium main web page and the Eclipse Temurin web page include several download buttons for downloading different Eclipse Temurin distribution.
Procedure
Choose one of the following options to download an Eclipse Temurin distribution:
From the Adoptium home web page or from the Eclipse Temurin project page , click one of the following buttons from the web page:
-
Latest LTS Releasebutton that preselects Red Hat build of OpenJDK 17 for the platform that it detects you are using and immediately begins downloading that selection. -
Other platforms and versionsbutton that directs to a selection of all platform and version options, where you can choose the distribution that best suits your needs from the various formats such as archives, JRE archives and installers. -
Release archivebutton that directs to a selection of latest releases, older releases, and nightly beta releases. Eclipse Adoptium provides older releases and beta releases for development purposes only. Beta releases contain the most recent changes delivered into Red Hat build of OpenJDK, which you’ll find useful for verifying fixes in development mode. Beta releases are not considered production ready and are not directly supported by Red Hat.
-
- Use the Eclipse Adoptium API, see the Swagger UI v3 documentation Eclipse Temurin.
- From the Eclipse Temurin Docker Hub Official Images, see the eclipse-temurin documentation (docker hub ).
- Use the Eclipse Temurin Marketplace and Marketplace API, by going to the AdoptiumTM Marketplace web page. This web page lists various distributions, such as the Red Hat build of Red Hat build of OpenJDK and Eclipse Temurin distributions. Additionally, you can make a request to the Eclipse Adoptium Marketplace API v1 to serve up these distributions.

Chapter 4. Distribution selection
Eclipse Temurin produces several distributions of Red Hat build of OpenJDK. Red Hat provides support for a subset of these distributions.
All Eclipse Temurin distributions of Red Hat build of OpenJDK contain the JDK Flight Recorder (JFR) feature. This feature produces diagnostics and profiling data that can be consumed by other applications, such as JDK Mission Control (JMC).
To help select a distribution that is right for your needs, see Platform Coverage for Red Hat Support of Eclipse Temurin (Red Hat Customer Portal).
