I am trying to upgrade atg from 5.6.1 to newer version 6.0.0

The following error happens when atg Dynamo server starts.
**** Error Wed Apr 16 06:57:30 PDT 2003 1050501450112 /atg/scenario/ScenarioManager Unable to update process /recorders/adminregister.sdl CONTAINER:atg.process.ProcessException: Could not perform XSL transformation dynamosystemresource:/atg/scenario/definition/sdlToPdl.xsl on scenario /recorders/adminregister.sdl; SOURCE:java.lang.NullPointerException

How to reproduce the problem:

1. telnet to jtg-u80-1.sfbay ( root passwd: jtg-u80-1 )
2. cd /home/junzhong/tmp/Dynamo6.0.0/home/bin
3. start Dynamo server by executing the script ./startDynamo


With jdk1.3.1, Dynamo Server starts successfully without any problem.
The problem happens from jdk1.4

I have contacted ATG tech support. Below is his response.
