Wrong. The JSON render renders the child nodes in exactly the order as returned from the repository. The properties of nodes (or resources) are of course not returned in any defined order simply because the JCR spec does not define an order amongst the properties ... The JSON render does not create an intermediate JSONObject but directly writes the data out thus keeping the order.
