      return new TrustedListenableFutureTask<V>(Executors.callable(runnable, result));
    }
docs: Creates a {@code ListenableFutureTask} that will upon running, execute the given {@code
  Runnable}, and arrange that {@code get} will return the given result on successful completion.
  
  @param runnable the runnable task
  @param result the result to return on successful completion. If you don't need a particular
  result, consider using constructions of the form: {@code ListenableFuture<?> f =
  ListenableFutureTask.create(runnable, null)}
