> 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.
