Image Rotate Problem?

Question

I'm using Jimi Rotate class to rotate the image. It is rotating the image. But what happens black lines are added around the image.
How to solve this problem?
public Image rotateImage(BufferedImage bi, int pos)
        ImageProducer source = bi.getSource();
        Rotate rot;
        if(pos == 0)
            rot = new Rotate(90);
        else
            rot = new Rotate(-90);
        FilteredImageSource fis = new FilteredImageSource(source, rot);
        return new JimiCanvas().createImage(fis);
}

I have tried with another code also for rotate image. It is working properly. But what happens while using remote desktop connection and using this application to rotate the image. The Image is changing into Blue Color. Sometime In single PC itself I'm getting this problem.
How to solve this problem.
public Image rotateImage(BufferedImage bi, int pos)
        new_bi = new BufferedImage(bi.getHeight(),bi.getWidth(),bi.SCALE_FAST);
        Graphics2D g2d = new_bi.createGraphics();
        AffineTransform at = g2d.getTransform();
        AffineTransform rotation = new AffineTransform();
        if(pos == 0)
            rotation.rotate( (-1) * Math.PI / 2, bi.getWidth() / 2, bi.getHeight() / 2);
        else
            rotation.rotate( Math.PI / 2, bi.getWidth() / 2, bi.getHeight() / 2);
        g2d.transform(rotation);
        if(pos == 0)
            g2d.drawImage( bi, null, (bi.getWidth() / 2 - new_bi.getWidth() / 2 ) * -1, (bi.getHeight() / 2 - new_bi.getHeight() / 2));
        else
            g2d.drawImage( bi, null, (bi.getWidth() / 2 - new_bi.getWidth() / 2 ), (bi.getHeight() / 2 - new_bi.getHeight() / 2) * -1);
        g2d.setTransform(at);
        return new JimiCanvas().createImage(new_bi.getSource());
}
