Re: ImageIO memory issue

:) No, I do want to keep a reference, but I tried to Isolate the
memory problem.
When I run this code and I load 2 JPEG images (1.88 MB each), the
program uses 43 MB of
my memory. Why doesn't the memory get released?

Here is some of my code (where I load the images):

/**

 */
package thumbnail;

import java.awt.*;
import java.awt.geom.AffineTransform;
import java.awt.image.*;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

/**

public class Thumbnail {
    private Image smallThumbnail = null;
    private Image normalThumbnail = null;

    public Thumbnail(File imageFile, int fileID){
        try {
            ImageIO.setUseCache(false);
            ImageIO.read(imageFile);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    public Image getSmallThumbnail(){
        return smallThumbnail;
    }

    public Image getNormalThumbnail(){
        return normalThumbnail;
    }

    public int getWidthNormalThumbnail(ImageObserver obs){
        return normalThumbnail.getWidth(obs);
    }

    public int getHeightNormalThumbnail(ImageObserver obs){
        return normalThumbnail.getHeight(obs);
    }

    public int getWidthSmallThumbnail(ImageObserver obs){
        return smallThumbnail.getWidth(obs);
    }

    public int getHeightSmallThumbnail(ImageObserver obs){
        return smallThumbnail.getHeight(obs);
    }
}
