Java BufferedImage to clipboard gives IIOException

I'm trying to copy a image (held in a BufferedImage object) to the clipboard. I'm using the code from this answer.

When trying to paste the image in a program, simply nothing happens. GIMP shows a message saying no image data was found in the clipboard.

I also tried the workaround from this article. Effectively, I changed the constructor to this:

        Robot robot = new Robot();
        Dimension screenSize  = Toolkit.getDefaultToolkit().getScreenSize();
        Rectangle screen = new Rectangle( screenSize );
        BufferedImage i = robot.createScreenCapture( screen );

        // ----- start of changes from workaround -----
        // Work around a Sun bug that causes a hang in "sun.awt.image.ImageRepresentation.reconstruct".
        new javax.swing.ImageIcon(i); // Force load.
        BufferedImage newImage = new BufferedImage(i.getWidth(null), i.getHeight(null), BufferedImage.TYPE_INT_ARGB);
        newImage.createGraphics().drawImage(i, 0, 0, null);
        i = newImage;
        // ----- end of changes from workaround -----

        TransferableImage trans = new TransferableImage( i );
        Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
        c.setContents( trans, this );

This doesn't make it work, but it changes the behavior: Everytime I try to paste, my program displays the following exception in the console:

I'm on Ubuntu 11.10 x64 and tried pasting to various programs, among them LibreOffice Draw, LibreOffice Writer, GIMP, InkScape.

mw@nb999:~$ java -version
java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

Has anybody run into the same trouble? Did I do something wrong, is it a Java bug, is there a workaround?

EDIT : I'm using a quite dirty workaround at the moment. I took a small Python script I found on stackoverflow, write the Image to file from Java and feed the file to this script which copies it to the clipboard. Of course, this is everything but platform independent. So I'm still hoping for a solution in Java.

Yours, Max Weller

You are probably running OpenJDK, which does not support writing JPEG images. You could try to switch to Sun/Oracle Java.
