drawimage exception

[java2d]

I am using drawimage method to draw a BufferedImage to another BufferedImage.
But got exceptions like:

java.lang.NoClassDefFoundError
        at
sun.awt.motif.X11CachingSurfaceManager.isDestSurfaceAccelerated(X11CachingSurfac
eManager.java)
        at
sun.awt.image.CachingSurfaceManager.getSourceSurfaceData(CachingSurfaceManager.j
ava)
        at sun.java2d.SurfaceData.getSourceSurfaceData(SurfaceData.java)
        at sun.java2d.pipe.DrawImage.renderImageCopy(DrawImage.java)
        at sun.java2d.pipe.DrawImage.copyImage(DrawImage.java)
        at sun.java2d.pipe.DrawImage.transformImage(DrawImage.java:973)
        at sun.java2d.pipe.ValidatePipe.transformImage(ValidatePipe.java:220)
        at sun.java2d.SunGraphics2D.drawImage(SunGraphics2D.java:2993)

my source code like:
        Graphics2D g2d = (Graphics2D) watermarked_image.getGraphics();                
       
        //Create an alpha composite of 40%
        float opacity = 0.4f;
        AlphaComposite alpha = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, opacity);
        g2d.setComposite(alpha);        
               
        g2d.drawImage(added_image, 0, 0, null);
        g2d.dispose();

where watermarked_image and added_image are two BufferedImage.


Any one has idea?

   Hello,

   This exception doesn't make sense.
   Your Java installation seems to be broken or corrupted. You may want
   to try and reinstall it.

   If it still happens, please let us know your configuration (java version,
   os version), and provide a small test case reproducing the issue.

   Thanks,
     Dmitri

This problem is solved by constructing BufferedImage correctly.
But still not sure why it is such exception thrown out.
Can't find underline source code.

Please post the code which reproduces the problem. We can't do much if we can't reproduce the issue.
