Icons not getting antialiased / appearing blurry

[HiddenMachine3]

There appears to be alot of distortion and artifacts when using small icons in JLabels and JButtons.
Here is the code I am using to test this:

import com.formdev.flatlaf.FlatDarculaLaf;
import jiconfont.icons.font_awesome.FontAwesome;
import jiconfont.swing.IconFontSwing;

import javax.swing.*;
import java.awt.*;

public class Main {
    public static void main(String[] args) throws UnsupportedLookAndFeelException {
//        LookAndFeel laf = new NimbusLookAndFeel();
        LookAndFeel laf = new FlatDarculaLaf();
        UIManager.setLookAndFeel(laf);
        UIManager.put(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        UIManager.put("useSystemAAFontSettings", "on");
        UIManager.put("swing.aatext", "true");
        System.setProperty("awt.useSystemAAFontSettings","on");
        System.setProperty("swing.aatext", "true");
        UIManager.getDefaults().put(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);

        IconFontSwing.register(FontAwesome.getIconFont());

        JFrame frame = new JFrame("Test Window");
        JPanel content = new JPanel(new BorderLayout());

        JButton button = new JButton("Hello");
        button.setPreferredSize(new Dimension(100, 50));
        button.setIcon(IconFontSwing.buildIcon(FontAwesome.ARROW_LEFT, 40));
        content.add(button, BorderLayout.CENTER);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setContentPane(content);
        frame.pack();
        frame.setVisible(true);
    }
}

This doesn't seem to work on Windows 10. I am using Jiconfont to create the icons from FontAwesome . This issue seems to be present regardless of the LookAndFeel.

This is the result I am getting, where the anti aliasing is not working on the icons:

Please tell me a way to work around this. A workaround suggested by someone on stackoverflow , but that just makes it more verbose
Edit: it seems that the above answer also doesn't have antialiasing.

I'm beginning to think that it might just have to do with the jdk itself, or the OS I'm using to run this

[HiddenMachine3]

The problem seems to be deeper than I thought.

I just tested the app on a different OS : Ubuntu , and the antialiasing is actually working.

The antialiasing didn't work on Windows, but did work on Ubuntu.

I'm starting to think that its probably a problem with how the jdk performs antialiasing based on OS, or maybe how jIconFont performs antialiasing based on OS, or some OS forced featured that controls antialiasing.

I'm using ikonli now, as this issue is a bummer. Someone pointed out to me that the problem is in jiconfont itself

Hi @HiddenMachine3! Sorry, I'm discontinuing this project as there are newer and better ones.
Ikonli is great.
