Is there any analog to a 'finally' in jQuery AJAX calls?

Question

Is there a Java \'finally\' analogue in jQuery AJAX calls? I have this code here. In my always I throw an exception, however I ALWAYS want it to go to the

The below suggestions will not work in jQuery, because jQuery's promise implementation does not handle errors thrown in methods passed to then. I am only leaving them here as an illustration of what could be possible if jQuery was promises/A+ compliant. As Bergi rightly points out, you will have to manually wrap your code in your own try catch block.

call.xmlHttpReq = $.ajax({
    url : url,
    dataType : 'json',
    type : 'GET'
}).then(function(processedDataOrXHRWrapper, textStatus, xhrWrapperOrErrorThrown) {

   throw "something";

}).always(function() {

    alert("i want to always run no matter what");
});

Although I'm not sure if jquery's promise supports always, an alternative would be to use then (again) and pass the same function as both successHandler and errorHandler, like this :

call.xmlHttpReq = $.ajax({
    url : url,
    dataType : 'json',
    type : 'GET'
}).then(function(processedDataOrXHRWrapper, textStatus, xhrWrapperOrErrorThrown) {

   throw "something";

}).then(function() {

    alert("i want to always run no matter what");
},
function() {

    alert("i want to always run no matter what");
});
