Blocked Permission: ("java.util.PropertyPermission" "http.agent" "write") when trying to open a URL connection

Recommended Posts

I'm trying to read in item prices via the Runescape wiki API, but they block generic requests from anything with the default user agent of Java/{version}, so you have to use:

System.setProperty("http.agent", "Chrome");

In order to not get blocked by them. However, this line seems to be blocked by the OSBot client, because when I have it added I get the error:

Blocked permission: ("java.util.PropertyPermission" "http.agent" "write")

I assume there's a reason the client blocks this, but I'm not sure why. Is there an alternative or a workaround? Here is my full code:


public static JsonObject loadItemPrices() throws IOException {
        String sURL = "https://prices.runescape.wiki/api/v1/osrs/latest";

        URL url = new URL(sURL);
        URLConnection request = url.openConnection();
        JsonParser jp = new JsonParser();
        JsonElement root = null;
        System.setProperty("http.agent", "Chrome");
        try {
            root = jp.parse(new InputStreamReader((InputStream) request.getContent()));
        } catch(Exception e) { 
        JsonObject obj = root.getAsJsonObject();
        JsonElement element = obj.get("data");
        JsonObject data = element.getAsJsonObject();
        return data;
