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 for Eclipse Temurin
Red Hat will support select major versions of Eclipse Temurin in its products. For consistency, these versions match the Oracle JDK versions that are designated as long-term support (LTS).
For more information about Red Hat’s support policy for Eclipse Temurin and the supported operating systems for each available version of Eclipse Temurin, see the Eclipse Temurin Life Cycle and Support Policy.
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 Adoptium Working Group. Eclipse Temurin is based on the upstream OpenJDK 8u, OpenJDK 11u, OpenJDK 17u, OpenJDK 21u, and OpenJDK 25u projects; and it includes the Shenandoah Garbage Collector from version 11 onward.
Eclipse Temurin does not vary structurally from the upstream distribution of OpenJDK. Eclipse Temurin shares the following similar capabilities as OpenJDK:
Multi-platform
Red Hat offers support for Eclipse Temurin on Microsoft Windows, RHEL and macOS, so that you can standardize on a single Java platform in numerous environments, such as desktop, data center, and hybrid cloud.
Frequent releases
Eclipse Temurin delivers quarterly updates of JRE and JDK for the OpenJDK 8, OpenJDK 11, OpenJDK 17, OpenJDK 21, and OpenJDK 25 distributions. These updates are available as RPM packages, MSI installers, archive files, and containers.
Long-term support (LTS)
Red Hat supports the recently released Eclipse Temurin versions 8, 11, 17, 21, and 25. For more information about the support lifecycle, see Eclipse Temurin Life Cycle and Support Policy.
Chapter 3. Downloading Eclipse Temurin distributions from the Eclipse Adoptium web site
You can download Eclipse Temurin distributions from numerous sources, such as the Eclipse Adoptium web site.
Both the Eclipse Adoptium main web page and the Eclipse Temurin web page provide several different options for downloading different Eclipse Temurin distributions.
Procedure
From the Eclipse Adoptium home page or from the Eclipse Temurin project page, choose any of the following ways to download an Eclipse Temurin distribution:
- Option 1: Download the latest version directly
- Click the Download Temurin button. This preselects the latest available Eclipse Temurin version for the platform that it detects you are using and immediately begins downloading that selection.
- Option 2: Download a selected version directly
Click the Other Downloads link. This opens the Latest Releases tab where you can download Eclipse Temurin for a variety of platform and version options. You can choose the distribution that best suits your needs from the various formats such as archives, JRE archives, and installers.
By default, the Other Downloads link opens the download page for the latest available LTS version. The All Versions tab includes a series of filters that you can use to find and download the Eclipse Temurin distribution for a specific version, operating system, and architecture.
- Option 3: Use another way to download beyond direct downloads
In the Latest Releases tab for a specific version or all versions, scroll down to the Other ways to download Temurin section of the page. The available options in that section provide different ways to obtain an Eclipse Temurin distribution beyond performing a direct download.
For example:
- Temurin Containers provides a link to the official images for Eclipse Temurin in Docker Hub.
- Linux Repositories provides links to the Eclipse Adoptium Linux (RPM/DEB/APK) Installer Packages documentation page, which includes information about downloading RPM packages on RHEL from the packages.adoptium.net repository.
- Package Managers provides links to information about other package managers such as Homebrew, SDKMan, and WinGet.
- REST API provides links to information about the Eclipse Adoptium API and Swagger UI v3 documentation.
-
GitHub Actions provides a Github link for the
setup-javaaction. Other Downloads provides a link to nightly builds of Eclipse Temurin, which are a series of beta releases created as a development step towards a full release.
NoteEclipse Adoptium provides beta releases for development purposes only. Beta releases contain the most recent changes delivered into Eclipse Temurin, which are useful for verifying fixes in development mode. Beta releases are not considered production ready and are not directly supported by Red Hat.
- Option 4: Use the Eclipse Temurin Marketplace or the Marketplace API
- Click the Marketplace tab. This opens the Adoptium Marketplace web page, which lists various distributions, such as the Red Hat build of OpenJDK and Eclipse Temurin. Alternatively, you can send a request to the Eclipse Adoptium Marketplace API v1 to serve up these distributions.
Chapter 4. Distribution selection
Eclipse Temurin produces several distributions of OpenJDK. Red Hat provides support for a subset of these distributions.
All Eclipse Temurin distributions 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 Eclipse Temurin Life Cycle and Support Policy.
