Users can not install 6u10 by using the DT's javascript flow

It is found that both jre 6u10 online bundle and kernel bundle (referenced by the public dtoolkit.xml from java.com) can not be installed

*** Tested configuration
- x86 XP, win 7
- IE, FF

*** Step to reproduce:
0) Make sure the system has no jre 6u10
1) Use the DT's javascript to install jre 6u10 (online bunlde or kernel bundle)

eg:
<script src="http://java.com/js/deployJava.js"></script>
    <script LANGUAGE="javascript">
        deployJava.setInstallerType("kernel");
        deployJava.installJRE("1.6.0_10");
    </script>

If the jre 6u10 installation failed with the error message" Invalid command line argument. Consult the Windows Installer SDK for detailed command line help", then the issue is reproducible

In fact, these bunlds are invoked and fail to install:
jre-6u10-windows-i586-p-iftw-k.exe
jre-6u10-windows-i586-p-iftw.exe
