The following test reveals a few problems with ImageIO.read(File) method
on 64-bit Solsparc and Windows (build 1.4.1-beta-b06):

import java.io.*;
import javax.imageio.*;
import java.awt.image.*;

public class Test {
    public static void main(String args[]) {
        File fileSource = new File(args[0]);

        System.out.println("fileSource = " + fileSource);
        try {
            BufferedImage bufferedImage = ImageIO.read(fileSource);
            System.out.println("bufferedImage = " + bufferedImage);
        } catch(Exception e) {
            System.out.println("Unexpected exception.");
            e.printStackTrace(System.out);
        }
        System.out.println("End of the test.");
        System.exit(1);
    }
}

To reproduce the failures you should pass any jpeg or gif image to Test class.

1. The test crashes VM on 64-bit Solsparc (with -d64 -server -Xcomp options).

       4501529 JAVA VM crashes uses Java Advanced Imaging
       
   that was closed as duplicate of
   
       4520884 ImageI/O JPEG encoder causes VM crash on Win32
       
   I borrowed the source code (and cut it) from 4501529. #4501529 reveals
   the crash during writing an image. However, my test observes the crash
   even earlier - during reading an image.
   

2. The test completes, but hangs up on Windows. This failure was
   observed with java_g wrapper against Client and Server VMs. I
   used a machine with "Microsoft Windows 2000 [Version 5.00.2195]".

   "End of the test." string means that the last line of Test class has
   been reached. However, the test hangs up and I could not stop it even
   with Ctrl+C.


This bug affects the test

    nsk/regression/b4501529
    
from testbase_nsk.

The test will appear in the r14 release of testbase located at
