FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)


FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Unlimited-strength encryption jars are installed.

A DESCRIPTION OF THE PROBLEM :
I use 1.4.1 to write a keystore to a file, and have no problems reading it back with 1.4.1 (any version of 1.4.1, i.e. 1.4.1_01 through 1.4.1_03). When I try reading it with 1.4.2, I get a StreamCorruptedException.

I found similar problems described in two forum messages, without resolutions.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
(line number in Main.main may be incorrect)
java.io.StreamCorruptedException: invalid stream header
at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:737)

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
// sample code for reading from keystore;
// use similar code to generate the keystore and put some keys in it
import java.io.*;
import java.security.*;

public class Main {
  public static void main(String[] args) {
    try {
      final String keyStoreType = "JCEKS";
      final Provider provider = Security.getProvider("SunJCE");
      final char[] keystorePW = ...; // put a password here
      File keyStoreFile = new File("keystore"); // put a filename here
      KeyStore keyStore = KeyStore.getInstance(keyStoreType, provider);

      final InputStream keyStoreStream = new FileInputStream(keyStoreFile);
      keyStore.load(keyStoreStream, keystorePW);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

CUSTOMER SUBMITTED WORKAROUND :
