Hello,

The issue you are facing with Java applications crashing due to the error message "Unable to verify the Deployment Rule Set JAR file due to certificate expiration" is likely related to the Java Deployment Rule Set (DRS) and certificate validity.

Deployment Rule Set (DRS) is a feature introduced in Java to control which Java applets or Web Start applications are allowed to run based on a set of rules defined by administrators. This mechanism allows organizations to establish security policies for running Java applications.

The error message you encountered indicates that the Java Runtime Environment (JRE) is unable to verify the signature of the Deployment Rule Set JAR file due to certificate expiration. This typically happens when the certificate used to sign the Deployment Rule Set JAR file has expired, making it invalid.

To resolve this issue, you can try the following steps:

Update Java: Make sure you have the latest version of Java installed on your system. Newer versions of Java may have updated certificates that resolve the issue.

Clear Java Cache: Clear the Java cache on your system to remove any outdated or expired certificates. Follow these steps:

Open the Windows Control Panel.

Find and open the "Java" control panel applet.

In the "General" tab, click on the "Settings" button under the "Temporary Internet Files" section.

Click on the "Delete Files" button, check the "Trace and Log Files" and "Cached Applications and Applets" options, and then click "OK."

Check Deployment Rule Set: If you are using a Deployment Rule Set, make sure that it is up to date and that the JAR file is signed with a valid, non-expired certificate.

Check System Time and Date: Ensure that the system's date and time are correct. Incorrect system time can cause certificate verification issues.

Check Internet Explorer Settings: Since you mentioned you are using IE11 mode, check Internet Explorer settings related to certificates and security. Ensure that security settings are not preventing proper certificate validation.

Try Other Browsers: Test your Java applications on different browsers like Google Chrome, Mozilla Firefox, or the new Microsoft Edge to see if the issue persists. Sometimes, issues may be specific to certain browsers or their settings.

If none of the above steps resolve the issue, consider reaching out to Oracle Support for further assistance. They may provide additional guidance or solutions specific to your Java environment and configurations.
