OpenJDKbased

OpenJDKbased refers to software, environments, or base images that are built on top of the OpenJDK project as the primary Java runtime and standard library. It signals that the Java execution environment provided by the OpenJDK codebase is the foundation, rather than a separate or vendor-locked JDK.

OpenJDK is the community-driven, open source implementation of the Java Platform, Standard Edition. OpenJDK-based software relies on the OpenJDK JDK or JRE binaries, adheres to Java SE APIs, and aims for compatibility with Java specifications.

Licensing and redistribution: OpenJDK is distributed under GPL v2 with the Classpath Exception, which affects how binaries can be redistributed. Many vendors provide OpenJDK-based builds under their own licenses and support terms, sometimes with commercial offerings.

Examples and scope: Notable OpenJDK-based distributions include Temurin (formerly AdoptOpenJDK), Liberica, Zulu, Red Hat OpenJDK, Amazon Corretto, and SAPMachine. OpenJDKbased images are commonplace in container deployments and cloud environments, where images may be labeled as openjdk-based.

Considerations: While OpenJDK strives for compatibility with Java SE, differences can exist between builds from different providers. Application testing is advised when moving between Oracle JDK and OpenJDK-based runtimes, or between different OpenJDK distributions.

Note: OpenJDKbased is a descriptive term rather than an official Java Platform designation, used to indicate reliance on the OpenJDK codebase as the basis for a project or product.
