Thanks for reviewing it. Yes, I still need a reviewer for this fix.

I agree that it's better to add a method to save the system properties

Properties.getProperty doesn't have permission check and thus there is
no need for a privileged block for this method. Will think about the
method name getSavedSystemProperty will work, or maybe
