javaws -J-Dkernel.background.download=false process shouldnt spawn BackgroundDownloader java process

Reproducile Step:
a) Install Kernel JRE
b) Kill background Downloader process.
c) Execute : javaws -J-Dkernel.background.download=false http://..../some.jnlp

Expected result:
BackgroundDownloader java process shouldnt start.
I am able to reproduce this problem with promoted b13 bundle.

M/cs - jlab406.india.sun.com - Windows XP and urti069.india.sun.com - Vista
But not reproducible in all m/cs. Here is the output from jlab406.india.sun.com

a) Install Kernel JRE
b) kill the running Background Downloader
c) Run a javaws with -J-Dkernel.background.download=false
d) check for the backgrounddownloader process.
