关于Fiori应用sandbox JavaScript的两个疑问

1. When I test, Ifound this json file is loaded twice with two different url. Actually the content is exactly the same. Why?

When I debug, I find it is because sandbox.js has loaded two different json files in line 278 and 288. Is this expected behavior?

1. why we should manually load this file? As far as I know, it should never be loaded by application manually.
