Can jQuery promises be chained with Ember.RSVP.Promise's?

Question

I need help to understand some promises logic. Here is what I want to achieve - with jQuery I make get request, then I chain it with my promise which makes some checks, my code:

http://jsbin.com/UVEpurU/1/edit

function checkInfoPromise(r) {
    var ok = true,
        promise = Ember.RSVP.Promise(function(resolve, reject) {
        if(ok) {
            return resolve(r);
        }
        else {
            return reject(r);
        }
        });
    return promise;
}

var requestPromise = $.get('/')
.then(function(r){
    return checkInfoPromise(r);
});

requestPromise.then(function(r) {
    console.log(r);
}).fail(function(r) {
    console.log('fail');
});

and it doesn't work as I expect. Documentation says they should work fine with each other, but they don't or my code is incorrect.

Same logic with jQuery+jQuery works fine:

And Ember+Ember works:

I don't think the two promise implementations are chainable. You'd want to wrap the jquery promise inside of an Ember promise.

var requestPromise = new Ember.RSVP.Promise(function(resolve, reject) {
    $.get("/", resolve).fail(reject);
});
