and you can reify the stack, see below.

Lukas, I think you should store a special singleton object instead of null
in the object array (objectValues) because currently there is no way to 
know if
null is null or a scalar.

Also I think we should have a way to ask to an overload of 
AsymRunnable.call()
to throw an exception that will be thrown by ret() in the coroutine and 
vice versa.

Rémi

     Coroutine coroutine = new Coroutine() {
       @Override
       protected void run() {
         int i = 3;
         int j = 4;
         Object o = null;
         int k = 2 + myYield();
       }

       private int myYield() {
         yield();
         return 0;
       }
     };

     Coroutine.yield();

     CoroutineFrame[] frames = coroutine.serialize();
     for(int i=0; i<frames.length; i++) {
       CoroutineFrame frame = frames[i];
       frame.dump();
       System.out.println("object values 
"+Arrays.toString(frame.objectValues));
       System.out.println("scalar values 
"+Arrays.toString(frame.scalarValues));
     }

prints:
frame: CoroutineBase.startInternal at 49 (3 locals, 0 expressions, 0 monitors)
object values [fr.umlv.async.io.SerializeMain$1 at 69adff28, null, null]
scalar values [0, 0, 0]
frame: .run at 8 (5 locals, 1 expressions, 0 monitors)
object values [fr.umlv.async.io.SerializeMain$1 at 69adff28, null, null, 
null, null, null]
scalar values [0, 3, 4, 0, 0, 2]
frame: .myYield at 0 (1 locals, 0 expressions, 0 monitors)
object values [fr.umlv.async.io.SerializeMain$1 at 69adff28]
scalar values [0]
frame: Coroutine.yield at 6 (0 locals, 0 expressions, 0 monitors)
object values []
scalar values []
