Memory leak in java ImageIO.read()

Question

I am utilizing ImageIO.read(). The class which is called by the main method of the original App is this:

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

I have got the same memory issue with this code (JPEGReader). After a few trials, I found that calling reader.dispose() can solve this issue.

I give the method that I have modified. Hope it is helpful to you.

public BufferedImage readImage(File file) throws IOException, ImageReadException {
    colorType = COLOR_TYPE_RGB;
    hasAdobeMarker = false;

    ImageInputStream stream = ImageIO.createImageInputStream(file);
    try{
        Iterator<ImageReader> iter = ImageIO.getImageReaders(stream);
        while (iter.hasNext()) {
            ImageReader reader = iter.next();
            reader.setInput(stream);

            BufferedImage image;
            ICC_Profile profile = null;
            try {
                image = reader.read(0);
            } catch (IIOException e) {
                colorType = COLOR_TYPE_CMYK;
                checkAdobeMarker(file);
                profile = Sanselan.getICCProfile(file);
                WritableRaster raster = (WritableRaster) reader.readRaster(0, null);
                if (colorType == COLOR_TYPE_YCCK)
                    convertYcckToCmyk(raster);
                if (hasAdobeMarker)
                    convertInvertedColors(raster);
                image = convertCmykToRgb(raster, profile);
                return image;
            }
            finally {
                reader.dispose();
            }
        }
        return null;
    }
    finally {
        if (stream != null){
            stream.close();
        }
    }
}
