Adoptium

The Eclipse Adoptium Working Group is the successor of AdoptOpenJDK.

The main goal of Adoptium is to promote and support free and open-source high-quality runtimes and associated technology for use across the Java ecosystem. To do so the Adoptium Working Group (WG) builds and provides OpenJDK based binaries under the Eclipse Temurin project. In addition to Temurin the WG creates an open test suite for OpenJDK based binaries as part of the Eclipse AQAvit project.

The Adoptium Working Group was launched by Alibaba Cloud, Huawei, IBM,, Karakun AG, Microsoft, New Relic, and Red Hat in March 2021.

In May 2022, the Adoptium project announced the formation of the Adoptium Marketplace.

Eclipse Temurin
The Eclipse Temurin project produces Temurin, a certified binary build of OpenJDK. The initial release in October 2021 supported Java LTS 8, 11, 17, and 21. The name for the project, Temurin, is an anagram of the word runtime. Since 2023 the Adoptium Working Group members Azul Systems, IBM, Open Elements and Red Hat offer commercial support for Temurin.

History
Eclipse Adoptium originally started as AdoptOpenJDK. AdoptOpenJDK was founded in 2017 and provided enterprises with free and open-source Java runtimes.

In 2020, AdoptOpenJDK moved to the Eclipse Foundation project under the name Eclipse Adoptium. The working group produces binaries via the Eclipse Temurin project.
