Java application with a certificate from an untrusted source
Starting with Java 7 Update 51, applications with self-signed certificates are blocked by default. Applications of this type present the highest level of risk because publisher is not identified and the application may be granted access to personal data on your computer.
What to look for: •Dialog title: Application Blocked
•Publisher name: No publisher listed
•Message displayed: Your security settings have blocked a self-signed sandbox application from running.
What to do: • It is highly recommended to not run this type of application. However if you understand the risk and still want to run the application, you can add the URL of this application to Exception Site List, which is located under the Security tab of the Java Control Panel.
