    023     * {@code ExecutionException}, the exception's {@linkplain #getCause() cause}
    024     * comes from a failed task, possibly run in another thread.
    025     *
    026     * <p>{@code UncheckedExecutionException} is intended as an alternative to
    027     * {@code ExecutionException} when the exception thrown by a task is an
    028     * unchecked exception. This allows the client code to continue to distinguish
    029     * between checked and unchecked exceptions, even when they come from other
    030     * threads.
    031     *
    032     * <p>When wrapping an {@code Error} from another thread, prefer {@link
