### Motivation MixedProtocolClusterSpec nightly runs can pass their cluster join assertions but still fail in shutdownAll when the first seed ActorSystem is stopped before the joining nodes have left. On JDK 25 virtualized dispatcher runs this can leave remoting shutdown waiting until the actor-system-terminate phase times out. ### Modification Shut down ClusterTestKit actor systems in reverse registration order so joining nodes leave first while the seed is still available. ### Result Multi-ActorSystem cluster specs using shutdownAll keep the seed alive until dependent nodes have terminated, reducing shutdown timeout flakiness without reducing test coverage or weakening assertions. ### Tests - JDK 25 nightly-style: `sbt "cluster / Test / testOnly org.apache.pekko.cluster.MixedProtocolClusterSpec"` - 9 tests succeeded / 0 failed - `scalafmt --mode diff-ref=origin/main` - `scalafmt --list --mode diff-ref=origin/main` - `git diff --check` ### References None - nightly-builds.yml MixedProtocolClusterSpec shutdown timeout -- This is an automated message from the Apache Git Service.
