> The method {{TaskExecutorPartitionLifecycleTest#runInTaskExecutorThreadAndWait}} does not run the given runnable in the {{TaskExecutors}} main thread. Instead it will run it in an arbitrary thread of the {{RpcService}}.
> The reason why this does not cause test instabilities is that we execute operations which don't cause race conditions. However, in order to avoid spreading false friends I would suggest to get rid of this pattern. Moreover, I would question whether {{TaskExecutorPartitionLifecycleTest}} really needs access to the {{TaskExecutors}} internal state. I believe there is an easy way using the {{TaskExecutors}} public API to implement the tests.
