Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
DESede (triple DES) encryption using JDK 1.4.2 produce different result from JDK 1.3.1 or JDK 1.4.1.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile the sample code and execute:
java -client tahiti.util.DESEncryption key "0123456789"

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
This is the result I get when running with JDK 1.3.1 or JDK 1.4.1
