@reta Can you check the error from JDK 23: https://github.com/opensearch-project/notifications/actions/runs/11482952177/job/31981106157?pr=977. It shows Unsupported class file major version 67.

@reta to support java 23, jacoco need upgrade to 0.8.12, not sure whether have more libs need to upgrade.

Also java 23 is not LTS version, we might not rush for supporting this.

We don't do anything in particular to support it, beside just adding to build / test matrix. The main is build with JDK 23 now.
