> We experienced an issue where we tested behavior using the {{DirectExecutorService}} with the {{ExecutorService}} being shutdown already. The tests succeeded. The production code failed, though, because we used a singleThreadExecutor for which the task execution failed after the executor was stopped. We should add this behavior to the {{DirectExecutorService}} as well to make the unit tests be closer to the production code.
