The Eclipse Adoptium Working Group is the successor of AdoptOpenJDK.[2][3]

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.[4] To do so the Adoptium Working Group will build and provide OpenJDK based binaries under the Eclipse Temurin project.[5] In addition to Temurin the WG creates an open test suite for OpenJDK based binaries as part of the Eclipse AQAvit project.[6]

The Working Group has been launched by Alibaba Cloud, Huawei, IBM, iJUG, Karakun AG, Microsoft, New Relic, and Red Hat in March 2021.[1]


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 will produce binaries via the Eclipse Temurin project.


As of June 2021, there are 10 members [7]
