Eclipse Temurin is a relatively new distribution of OpenJDK from the Eclipse Adoptium community. It has become the distribution of choice for many Java developers since its first Java SE release in August 2021; with over half a billion downloads, it is the most popular build of OpenJDK in production.
We are expanding our support for Java applications by including support for Eclipse Temurin. Read on to learn more about the Temurin project and how Red Hat supports Temurin development and production use cases.
What is Eclipse Temurin?
The Eclipse Temurin project is a distribution of OpenJDK from Adoptium (formerly AdoptOpenJDK). It provides code and processes that support building high-quality runtime binaries and associated technologies for general use across the Java ecosystem. Temurin binaries are cross-platform, open-source licensed, and TCK-certified for Java SE.
Red Hat's support for Java
Red Hat is a longtime contributor to OpenJDK and open source projects like Red Hat JBoss Enterprise Application Platform, Quarkus, Hibernate, Keycloak, and others relevant for distributed cloud architectures and associated technology in the Java ecosystem. Red Hat supports OpenJDK in development and production with Red Hat Runtimes, Red Hat OpenShift, and directly via the Red Hat build of OpenJDK.
Developers can now use Eclipse Temurin, also supported as part of the Red Hat build of OpenJDK. Red Hat will support development and production use cases similar to the award-winning support that comes with the Red Hat build of OpenJDK.
Use Eclipse Temurin across platforms
Developers use Java to create modern, business-critical applications across industries. These applications span from the desktop to data centers and the cloud, and are deployed on multiple operating systems and platforms. With the inclusion of support for Eclipse Temurin, you can now also deploy Java applications across multiple Linux operating systems and cloud environments.
In addition to distributing and providing support for OpenJDK, the Red Hat portfolio of open source products also supports Java on Red Hat Enterprise Linux and Microsoft Windows. You can use these products to create, integrate, and automate modern business applications and processes and enable full-stack support from the operating system to application services from a single vendor.
If you are developing Java applications, you can go ahead and download RPMs or archives for your favorite operating systems. Red Hat provides production and development support for Linux and Windows distributions and development support for macOS, both physical and virtual environments.

AQAvit: Ensuring enterprise-grade quality
Eclipse AQAvit brings a curated set of additional testing to a standard Java runtime to ensure it meets a quality bar suitable for production use. As part of AQAvit's verification of Eclipse Temurin binaries, release artifacts are produced for 350,000+ automated tests on more than 100+ test machines and OS platforms.
AQAvit ensures builds meet the modern requirements, including containerized tests. The tests are categorized into the following:
- Security: Testing all known security vulnerabilities.
- Functional correctness: Using OpenJDK regression, functional, and key application/framework tests.
- Performance: Ensuring and achieving minimum throughput scores with published metrics.
- Scalability and durability: Meets minimum load and stress testing requirements.
