FULL PRODUCT VERSION :
8_u40 x64 b25 and b26

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.3.9600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
sccm/puppet

A DESCRIPTION OF THE PROBLEM :
Automated silent installations of this version will not work due to a certificate verification popup. The cmd window will not close due to the prompt thus config management systems will never get the correct exit code.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Attempt to silently install java on a fresh install while keeping the window open until finished.

start /w jdk-foobar.exe /s

You will see that it will successfully install, however the window will not close because of the certification prompt. SCCM and Puppet can not handle this as they are expecting a return of 0 when the window is closed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should be able to set a param to accept this prompt, or ignore it. Should be able to silent install without any issue.
ACTUAL -
Prompt stays open and configuration management tools can not handle the prompt.

REPRODUCIBILITY :
This bug can be reproduced always.
