/**

 * {@link Scheduler} to run code after a delay.
 * @param exec We need a Java {@link Executor} to apply the result
 * of the {@link CompletableFuture} and a Scala
 * {@link ExecutionContext} so we can use the Akka {@link Scheduler}.
 * An {@link ExecutionContextExecutor} implements both interfaces.
