[1.12] Need help render texture with DynamicTexture

[lamp3345]

I make the Custom Cape rendering with PNG image from URL. Current method seems bad performance (And its make game lag 2~ second after finished download texture).

 

Current Code :

 

    public static void setCapeURL(String url, boolean startup)
    {
        URL jurl = null;
        boolean noConnection = false;
        JsonUtil json = new JsonUtil();

        try
        {
            jurl = new URL(url);
        }
        catch (MalformedURLException e)
        {
            noConnection = true;
            e.printStackTrace();
            return;
        }

        if (CapeUtils.textureUploaded && !noConnection)
        {
            try
            {
                CapeUtils.CAPE_TEXTURE.put(GameProfileUtil.getUsername(), new DynamicTexture(ImageIO.read(jurl)));
                ExtendedConfig.CAPE_URL = Base64Utils.encode(url);
                ExtendedConfig.save();
                CapeUtils.textureUploaded = false;
            }
            catch (MalformedURLException e)
            {
                if (IndicatiaMod.MC.player != null)
                {
                    IndicatiaMod.MC.player.sendMessage(json.text("Missing protocol or wrong URL format").setStyle(json.red()));
                }
                e.printStackTrace();
                return;
            }

 

I've changed to use Thread, but I don't know whats wrong with it.

It throw message "No OpenGL context found in the current thread."

 

public class ThreadDownloadedCustomCape extends Thread
{
    @Override
    public void run()
    {
        URL capeUrl = null;

        try
        {
            capeUrl = new URL("http://i.imgur.com/vXgIBgM.png");
            BufferedImage image = ImageIO.read(capeUrl);
            File pngFile = new File(IndicatiaMod.CONFIG, "custom_cape.png");
            ImageIO.write(image, "png", pngFile);
            Thread.sleep(5000);
            new ThreadReadCustomCape().start();
        }
        catch (MalformedURLException e)
        {
            e.printStackTrace();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        catch (InterruptedException e)
        {
            e.printStackTrace();
        }
    }
}

 

public class ThreadReadCustomCape extends Thread
{
    @Override
    public void run()
    {
        try
        {
            File pngFile = new File(IndicatiaMod.CONFIG, "custom_cape.png");

            if (pngFile.exists())
            {
                BufferedImage image = ImageIO.read(pngFile);
                CapeUtils.CAPE_TEXTURE.put(GameProfileUtil.getUsername(), new DynamicTexture(image));
            }
        }
        catch (MalformedURLException e)
        {
            e.printStackTrace();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}

You shouldn't use custom capes website or something unless you are going to use advanced capes mod; thats fine. Dont get messed will all that code.
