The following test loads and initilizes all classes and interfaces from
jar-file, that is passed to the test as an argument.

import java.io.*;
import java.util.*;
import java.util.jar.*;

public class Bug {
    public static void main(String args[]) {
        if (args.length < 1) {
            System.out.println("TEST FAILED.");
            System.out.println("Cannot find JAR file.");
            System.exit(2);
        }

        JarFile jarFile = null;

        try {
            jarFile = new JarFile(args[0]);
        } catch (IOException e) {
            System.out.println("TEST FAILED.");
            System.out.println("Cannot create JarFile.");
            System.exit(2);
        }

        Enumeration enumeration = jarFile.entries();

        try {
            for (; enumeration.hasMoreElements(); ) {
                JarEntry jarEntry = (JarEntry) enumeration.nextElement();
                String fileName = jarEntry.getName();
                int j = fileName.lastIndexOf(".class");

                if (j != -1) {
                    String className = fileName.substring(0, j);
                    className = className.replace('/', '.');

                    try {
                        Class initClass = Class.forName(className);
                        System.out.println("Class loaded: " + initClass);
                    } catch (ClassNotFoundException e) {}
                }
            }
        } catch (OutOfMemoryError e) {
            System.exit(0);
        }
    }
}

I've run the test on all platforms in all modes against Mantis-b02 to load
classes from tools.jar file and used -XX:MaxPermSize=4M option.

I have observed two crashes:

1. on Solsparc machines (Ultra-10, 440MHz, 512Mb; Ultra-60, 400MHz, 512Mb),
   Server VM, -Xcomp mode

The test also used to crash Merlin-b92 VM with '4349254E560E43505000C1 01'
Error ID. See the bugs

    4675027 hotspot vm crashes when Perm Space filled up
    4533120 Customer seeing a crash while running BEA Weblogic in "-client"

Please, note the test crashes neither Server, nor Client Hopper-b12 VMs.
