Running the following code on a corrupted jpeg results in an error message
writen on std err output by JPEGCodec.decodeAsBufferedImage, but no exception
is thrown and no validity flag of the resulting JPEGDecodeParam allow the code
to actually detect there ever was a corruption. This flaw introduces corrupted
data in our flow.

Execution:
bash-2.03$ ./java draw XXX30_28.jpg
Corrupt JPEG data: premature end of data segment
##### Params -> isImageInfoValid=trueisTableInfoValid=true
bash-2.03$

Code:
import java.io.*;
import java.awt.*;
import java.awt.image.*;
import com.sun.image.codec.jpeg.*;

public class draw
{
public static void main(String args[]) throws Exception
{
try
{
         InputStream fis = null;
         JPEGImageDecoder decoder = null;
         BufferedImage bi = null;
                    long stamp = System.currentTimeMillis();
fis = new FileInputStream(args[0]);
         decoder = JPEGCodec.createJPEGDecoder(fis);
         JPEGDecodeParam p=decoder.getJPEGDecodeParam();
         PrintStream olderr = System.err;
         bi = decoder.decodeAsBufferedImage();
         p=decoder.getJPEGDecodeParam();
         if (p!=null)
         System.out.println("##### Params ->
isImageInfoValid="+p.isImageInfoValid()
         +"isTableInfoValid="+p.isTableInfoValid());
         else
         System.out.println("##### Params -> null");

            }
         catch(Exception e)
         {
         e.printStackTrace();
         }
}
}
