loadJSONOject() fails with compressed json sent by an API

Description

I use an API which now send me compressed json.
loadJSONObject() fails to load this type of JSON.

Expected Behavior

allow loadJSONObject() to get compressed json

Current Behavior

When you use loadJSONObject() to load a compressed json file, the code crashes.

Steps to Reproduce

Unfortunately I can't give you a link to this private API which return compressed json.
You must find one. Sorry.

Your Environment

I use an old version of processing (2.2.1) for some reasons (need Unfolding library in this case).
I don't know if we have the same problem under the latest version of Processing.

• Processing version: 2.2.1
• Operating System and OS version: windows
• Other information: compressed JSON provided by an API

Possible Causes / Solutions

I found a workaround which only works with compressed json. It seems to work. I don't really understand all the code lines inside.
Here, my code :

import java.net.*;
import java.io.*;
import java.util.zip.GZIPInputStream;

void setup(){
size(200,200);
JSONObject json=getData("http://bla-bla");  
JSONArray values = json.getJSONArray("something to get");
println(values.size()); 
noLoop();
}

JSONObject getData(String urlsite){
  StringList sb;
  JSONObject json = new JSONObject();
  try{
    URL url = new URL(urlsite);
    URLConnection conn = url.openConnection();  
    conn.setRequestProperty("Accept-Encoding", "gzip, deflate");
    BufferedReader in = new BufferedReader(new InputStreamReader(new GZIPInputStream(conn.getInputStream()), "UTF-8"));
    String readLine;
    sb = new StringList();
    while ( (readLine = in.readLine ()) != null) {
      System.out.println(readLine);
      sb.append(readLine + '\n');
    }
    json = parseJSONObject(sb.get(0));
    in.close();
  }catch (MalformedURLException e) {
    e.printStackTrace();
  } catch (IOException e) {
    e.printStackTrace();
  }
  return json;
}

I think it would be great if you can add an argument to loadJSONObject().
Something like loadJSONObject(filename / API URL, compressed json / not compressed json).

loadJSONObject() works fine with a URL when the server sends the file over gzipped with the correct headers. There's an outside chance that it's broken in 2.2.1, but it sounds more like the file/server configuration is messed up.
