Steps to reproduce:
1. install jre8 b81 promotion build on win7-x86
2. After installation, if you see C:\Windows\Sun\Java\Deployment\deployment.properties gets created automatically with the following contents, the issue is reproduced:
=====================
#System Deployment Properties
#Thu Mar 21 09:06:08 CST 2013
deployment.security.level=HIGH
=====================

This could not be seen with 7u21.

Update -
If we install the JRE (7u25, and I think the same for 7u21) with some args like
jre-7u25-fcs-bin-b07-windows-i586-17_apr_2013.exe WEB_JAVA_SECURITY_LEVEL=VH
then I can see such a file got generated - C:\Windows\Sun\Java\Deployment\deployment.properties
====================
#System Deployment Properties
#Wed Apr 24 07:50:11 CST 2013
deployment.security.level=VERY_HIGH
==================

So the issue applies to 7u, too, now.
