Java swing BasicTextFieldUI painting ISSUE

Question

I am working on a project, in which I need to to change the style of JTextFields. I extended the BasicTextFieldUI, and overriden the paintSafely method, but, when it draws the component, it draws a border (even if the border is setted to null). I've tryed to look inside the BasicTextUI class, to see what could draw that border, and I didn't find anything.

Question,

Why will this code create a border around components?

This is my code:

public class CustomTextField extends BasicTextFieldUI{
    
    int borderThickness, edgeRoundness;

    @Override
    protected void paintSafely(Graphics g) {
        
        JComponent c = (JComponent)this.getComponent();
        Graphics2D g2 = (Graphics2D)g;
        g2.setColor(c.getBackground());
        
        borderThickness = 2;
        edgeRoundness = 20;
        
        g2.setColor(c.getForeground());
        g2.fillRoundRect(0, 0, c.getWidth(), c.getHeight(), edgeRoundness+5, edgeRoundness+5);
        g2.drawRoundRect(0, 0, c.getWidth(), c.getHeight(), edgeRoundness+5, edgeRoundness+5);
       
        g2.setColor(c.getBackground());
        g2.fillRoundRect(borderThickness, borderThickness, c.getWidth()-(int)(borderThickness*2.5), c.getHeight()-(int)(borderThickness*2.5), edgeRoundness, edgeRoundness);
        g2.drawRoundRect(borderThickness, borderThickness, c.getWidth()-(int)(borderThickness*2.5), c.getHeight()-(int)(borderThickness*2.5), edgeRoundness, edgeRoundness);
        
        
        super.paintSafely(g);
    }

}

What could be the mistake? Is there any other method used to paint the component?

You're not helping. If you know how to use swing, you can do some cool stuff. — CuriousCI, Feb 05 '19 at 18:46

I found the answe in this post! It seems that, by setting the border to null, I said to the PLAF to use it's own border. Swing JTextField how to remove the border?
