Name history error

So I made a command /names <username> to fetch a players previous names, but I get this error

Code (Text):

20.05 14:36:08 [Server] SEVERE Task BungeeTask([email protected], id=9, [email protected], [email protected], delay=0, period=0, running=true) encountered an exception

Anyone know how to fix it?

Also the errors comes from this medtod:

Code (Text):

private JSONArray readJsonFromUrl(String url) throws IOException, JSONException {
        try (InputStream is = new URL(url).openStream()) {
            BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
            String jsonText = readAll(rd);
            return new JSONArray(jsonText);
        }
    }

 

I just took the json code from bukkits api, since my plugin is a bungeecord one and bungee doesnt have json
