Answer 1

If you can't switch to another library or modify the code of this library to make it generic, the only other option would be to write a wrapper around this library which uses it, and properly supports generics.

So you would have your own JSONObject class which would contain an org.json.simple.JSONObject, would extend HashMap<String, Object> and implement Map<String, Object>, and would contain forwarding methods for all the methods of org.json.simple.JSONObject.

You would still have to put @SuppressWarnings("unchecked") in this class, but it would be limited to this class, and all the rest of your code could be free of generic warnings or the suppression of them.
