Java 8 has reached end of support and will be deprecated on January 31, 2026. After deprecation, you won't be able to deploy Java 8 applications, even if your organization previously used an organization policy to re-enable deployments of legacy runtimes. Your existing Java 8 applications will continue to run and receive traffic after their deprecation date . We recommend that you migrate to the latest supported version of Java .
