$.getSJON() behaving differently in v1.9.0

$.getSJON() behaving differently in v1.9.0

Hi folks,

I have a very simple script that is pulling data from a REST service and performing some knockout bindings with the results.  All works fine with jQuery 1.8.3

However when I drop in v1.9.0, the callback function doesn't appear to be called when there is an empty dataset.

    $.getJSON(self.newURL, function(data) {
        if (data !== null && data.Employees.length > 0) {
            vm.Employees(data.Employees); 
            vm.detailsClicked(true);
            vm.noEmployees(false);
        } else {
            vm.Employees([]);
            vm.detailsClicked(false);
            vm.noEmployees(true);
        }
    });

In the code example above, the "else" statement is not processed in jQuery 1.9.0, but works fine in v1.8.3

Thoughts?
