GWT native to long conversion

Hi.

I'm trying to convert js native number to GWT Long and send it over gwt-rpc. But I got very weird results..

public class gwtbugEntryPoint implements EntryPoint {    @Override    public void onModuleLoad() {      String data = "{\"type\":\"upd\", \"id\":123}";      ServerEvent serverEvent = JsonUtils.<ServerEvent>safeEval(data);      RootPanel.get().add(new HTML("GWT id="+serverEvent.getId()));    }    }  class ServerEvent extends JavaScriptObject {      protected ServerEvent() {      }    public final native String getType()/*-{ return this.type; }-*/;    public final Long getId(){      String idStr = _getId();      GWT.log("idSTr:" + idStr);      Long id = new Long(idStr);      GWT.log("id:"+id);      return id;  }    public final native String  _getId()/*-{ return this.id; }-*/;  }

console output:

idSTr:123

id:0

Can anyone explain me, how that could happen?
