deployment.expiration.check.enabled setting is ignored

FULL PRODUCT VERSION :


ADDITIONAL OS VERSION INFORMATION :
Windows 7 SP1 x64 7601

EXTRA RELEVANT SYSTEM CONFIGURATION :
Internet Explorer 9.0.8112.16421
Update versions: 9.0.23 (KB2898785)

A DESCRIPTION OF THE PROBLEM :
Deployment.config and deployment.properties exist in C:\Windows\Sun\Java\Deployment. deployment.expiration.check.enabled=false is ignored in the deployment.properties file while other settings (deployment.security.level) are visibly changed in the Java control panel. If the deployment.properties file is saved while the Java control panel is opened the deployment.expiration.check.enabled setting is excepted and warning prompt is suppressed in the browser (IE 9, 10, 11).

ADDITIONAL REGRESSION INFORMATION:
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) Client VM (build 24.0-b56, mixed mode, sharing)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create deployment.config and deployment.properties in C:\Windows\Sun\Java\Deployment. Include the following in the deployment.config file:

deployment.system.config=file:///C:/Windows/Sun/Java/Deployment/deployment.properties
deployment.system.config.mandatory=true

In the deployment.properties file:

deployment.webjava.enabled=true
deployment.security.level=HIGH
deployment.expiration.check.enabled=false

Use http://www.java.com/en/download/installed.jsp to receive the security prompt stating to upgrade. Kill IE (do not click later, block, or upgrade). Open the Java control panel. Open the deployment.properties file and save it. Visit http://www.java.com/en/download/installed.jsp and the prompt is now suppressed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The prompt warning that the version of Java is out of date should not prompt if the setting deployment.expiration.check.enabled is set to false (http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/jcp/properties.html).
ACTUAL -
The setting (deployment.expiration.check.enabled) is ignored.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Save the deployment.properties file while the Java control panel is opened.
