### What Disables TLS session extension for brokers. JDK 14 enabled TLS session tickets by default. This adds non-trivial CPU overhead for workloads that create short-lived TLS connections. For some older JDK-17 distributions, this can result in extreme CPU regressions, eg: https://bugs.openjdk.org/browse/JDK-8298381 calls out a case where a user running AK saw a significant performance regression. From what I can tell, the `kafka-run-class.sh` script is used for running servers or for running classes in the tools package which takes a dependency on the server module, so adding the flag here should be safe. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
