Certified version

The certified Java Runtime Environment (JRE) for AEMO Data Interchange applications is OpenJDK 21.

The published binary images can be found at https://jdk.java.net/java-se-ri/21.

Other distributions of the JRE may also work. Participants who choose an alternate JRE must first validate AEMO's Data Interchange applications operate correctly in a non-production environment before deploying to production.
