main.dart - Launches isolate and prints received messages.
=========
import 'dart:isolate';
main() {
  ReceivePort port = new ReceivePort()
  ..listen((msg) => print('msg: $msg'));

   Isolate.spawnUri(Uri.parse("isolate.dart"), [], port.sendPort);
}

isolate.dart - Isolate file.
============
import 'dart:async';
import 'dart:isolate';
void main(List<String> args, SendPort replyTo) {
  // This is OK.
  replyTo.send('Direct message');
  // This FAILS.
  new Future.value('Future message').then(replyTo.send);
}

I cannot reproduce this problem with the current dart VM on the command line.
The main isolate receives two messages and prints them both.

How, exactly, are you running the program?

Added NeedsInfo label.

It is web application, Dartium loads HTML page and runs Dart script.

This is probably because the dartium isolates don't support Timer (which is currently used by scheduleMicrotask).

Added Accepted label.

This problem was already been solved in spring 2013 (in old Isolate library) - see Issue #9135.

We recently had a regression where isolates in Dartium cannot use microtasks (which are usually used to complete Futures) and Timers.
I have already a CL prepared for fixing the microtasks. The timers might take longer.

I think the fix has landed, the example works now.
