Bug in Java2DFrameConverter

Hi guys. Java2DFrameConverter seems to work only with images of BufferedImage.TYPE_3BYTE_BGR(5) type. I've written some code that helps to check it out. I used square image with 4 quarters (rgb colors and last one left transparent). I tried to convert different types of this BufferedImage to Frame and than back. Resulting image (together with initial which is first) I draw on final image side by side:

import org.bytedeco.javacv.FrameConverter;
import org.bytedeco.javacv.Java2DFrameConverter;
import static org.bytedeco.javacpp.avutil.*;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.*;
import java.io.*;

    public static void main(){
        int types = 7;
        BufferedImage image = new BufferedImage(100,100,6);
        Graphics g = image.getGraphics();
        g.setColor(new Color(255, 0, 0, 255));
        g.fillRect(0, 0, 50, 50);

        g.setColor(new Color(0, 255, 0, 255));
        g.fillRect(50, 0, 50, 50);

        g.setColor(new Color(0, 0, 255, 255));
        g.fillRect(0, 50, 50, 50);

        BufferedImage result = new BufferedImage(types*100,100, 6);
        Graphics resultingGraphics = result.createGraphics();
        resultingGraphics.drawImage(image, 0, 0, 100, 100, null);

        for (int type=1; type<types; type++){
            BufferedImage typed = convertToBufferedImageOfType(image, type);

            Java2DFrameConverter converter = new Java2DFrameConverter();
            Frame frame1 = converter.getFrame(typed);

            Java2DFrameConverter newConverter = new Java2DFrameConverter();
            BufferedImage convertedBack = newConverter.getBufferedImage(frame1);

            resultingGraphics.drawImage(convertedBack, type*100,0, 100, 100, null);
        }

        try {
            ImageIO.write(result, "png", new File("resulting image"));
        } catch (Exception e){}
    }

    public static BufferedImage convertToBufferedImageOfType(BufferedImage sourceImage, int targetType) {
        BufferedImage image = new BufferedImage(sourceImage.getWidth(), sourceImage.getHeight(), targetType);
        image.getGraphics().drawImage(sourceImage, 0, 0, null);

        return image;
    }

Here is the result: You can see that output is not correct for most of the types. For 1st and 4th types we don't get anything. It might seem that type TYPE_4BYTE_ABGR(6) works fine, but it is not, you can see that by trying to use this type in FFmpegFrameRecorder. For example blue image (-1,-1,0,0) turns into yellow in video. It is so because AV_PIX_FMT_RGBA pixel format is used I think. For type TYPE_3BYTE_BGR(5) we use AV_PIX_FMT_BGR24 pixel format, so channels go to the proper places.
