If some one can take a look into this problem, I will appreciate it
greately.

I am trying to serialize simple JS Function.  I do not think it have
much relevance, but function I am trying to serialize looks like this:

function () {
  this.result = this.a + this.b;
  return this.result;
}

This is a snipet of the code which I am using to serialize it.  At this
moment function in question stored in remote_method variable:
....
Scriptable remote_method = ...;
....
 ByteArrayOutputStream baos = new ByteArrayOutputStream();

 ScriptableOutputStream sos = new ScriptableOutputStream( baos, scope
);
 sos.writeObject( remote_method );
 sos.close();
....

This is what I am getting in return:
