Can't yield from within an instance created by reflection

Is it meant to be like that, or will it be changed in the future?

The following code sample illustrates the problem:

class PinnedError {
   static final ContinuationScope scope=new ContinuationScope("TST");

   public PinnedError(String id) {
      Continuation.yield(scope);
   }

   public static void main(String[] args) {
      Continuation cont=new Continuation(scope,new Runnable() {
         public void run() {
            try {
               Constructor<PinnedError> constr =
PinnedError.class.getConstructor(new Class[] { String.class });
               constr.newInstance("Name");
            } catch (Exception e) { e.printStackTrace(); }
      }});

      cont.run();
   }
}


Execution results in:
