The following test crashes Server and Client VMs (build 1.4.1-beta-b06)
in all modes and on all platforms.

The test prepares ImageWriter and ImageOutputStream objects,
then sets output of the ImageWriter, disposes that writer and
then sets output again. Invokation of the second writer.setOutput()
crashes the VM.

The test also crashes VM without writer.dispose() command.

import java.io.*;
import java.util.*;
import javax.imageio.*;
import javax.imageio.stream.*;

public class Test {
    public static void main(String args[]) {

        // Retrieve ImageWriter
        Iterator writers = ImageIO.getImageWritersByFormatName("jpeg");
        ImageWriter writer = (ImageWriter) writers.next();

        // Retrieve ImageOutputStream
        ImageOutputStream ios;
        try {
            ios = ImageIO.createImageOutputStream(new File("OutputFile.jpg"));
        } catch(IOException e) {
            System.out.println("Unexpected exception.");
            e.printStackTrace(System.out);
            return;
        }
        System.out.println("ios = " + ios);
        if (ios == null)
            return;

        // Set ImageOutputStream to ImageWriter
        writer.setOutput(ios);
        System.out.println("1: output is set.");
        writer.dispose();
        System.out.println("writer is not disposed.");
        writer.setOutput(ios);
        System.out.println("2: output is set.");
    }
}

I have added this testcase into testbase_nsk, so that it
could be executed regularly by the SQE team. The test will
be shipped with 14 release of testbase_nsk; and the test
name will be:

    nsk/regression/b4660047
    
The test still reproduces the bug against Hopper-b10 on all
platforms.
