Return an empty dictionary instead of nil

[isbm]

If Uyuni API is called via REST interface, then it currently returns nil instead of an empty return type which is actually expected. Most of the time (up to 99%) it is an empty JSON dictionary.

To fix this, generated specs should also contain return type. This is not yet implemented in the spec generator.

Hey @isbm

Is that a custom Java parser?

Is that a custom Java parser?

In a hacking contest anything can happen. :wink: Yeah, I needed something get conceptually done literally in hours, so the concept works. I even started one in Java, but calculated that I will lose a lot of time to get something ready done, hence I crafted a very simple Python script that does the job good enough for now. But yes, this whole thing probably should be re-written in pure Java instead.

Maybe use an existing Java parser? There's a ton of them

But that's what I just wrote. It would be better to be done in Java instead. I did it quick&dirty, but for production it surely should be done in a better way.
