ClassNotFoundException on a completed Kernel JRE on Vista.

ClassNotFoundException on a completed Kernel JRE on Vista. sun.jkernel.DownloadManager.isJREComplete() is true and rt.jar is merged and bundles directory is removed. But Still I am getting the following ClassNotFoundException while loading all the public classes in Vista

WindowsXP this works fine and no CNFE.
Steps to reproduce:
a) Download and install Kernel JRE
b) wait till the bundles directory removed or isJREComplete() return true
c) Run the attached KerenlJREUtils.java by passing classes.log as argument. ( attached) redirect the err out put to a file.
