    025     * comes from a failed task, possibly run in another thread.
    026     *
    027     * <p>{@code UncheckedExecutionException} is intended as an alternative to
    028     * {@code ExecutionException} when the exception thrown by a task is an
    029     * unchecked exception. However, it may also wrap a checked exception in some
    030     * cases.
    031     *
    032     * <p>When wrapping an {@code Error} from another thread, prefer {@link
    033     * ExecutionError}. When wrapping a checked exception, prefer {@code
    034     * ExecutionException}.
