How can I crop an Image Object without using BufferedImage in Java

I wanted to make an spritesheet class for my java game . In past when i wanted to crop an image out of my spritesheet i used to use BufferedImage croping method , but its not working for me becuase i cant load the images when im loading images when they are in the jar file.

Now Im using Image Class . I searched an i found a crop method in Image class but i cant make it work .

what am i doing wrong ?

My SpriteSheet class :

package Maya.Core;

import java.awt.*;

public class Spritesheet{
    Texture sprite;
    public Spritesheet(String path){
        sprite = new Texture(path);     
    }

    public Image GetImage(Rect wantedRect){
        return sprite.image.crop(wantedRect.x,wantedRect.y,wantedRect.width,wantedRect.height);
    }    
}

My texture class:

public class Texture {
    public Image image;

    public Texture(String path) {
        Toolkit defaultToolkit = Toolkit.getDefaultToolkit();
        URL imageResource = Window.class.getClassLoader().getResource(path);
        image = defaultToolkit.getImage(imageResource);
    }
}
