Using IE, the application failed to launch using java web start mode via file access (http access works fine)

*** Tested Configurations:
- OS: x86 XP
- JRE: 7-fcs/ 6u26
- FX: - b39/ latest latest deploy scrum runtime
- Browser: IE

*** Steps to reproduce:
0) Install jre7-fcs
1) Install fx public sample
2) Install latest fx deploy scrum runtime
3) Use IE browser to invoke any html samples from the step#1
4) Click 'click to launch this app as webstart'

If the app fails to load with the following exception, then the issue is reproducible.
(The same issue does not occur if using Firefox)
