Pop-up Error "Your security settings have blocked an application from running due to missing a "Permissions" manifest attribute in the main jar"
Cause:
Note: This attribute check was added into the Java 7 branch starting with 1.7.0_45 and the Java 8 branch starting with 1.8.0_20 for preventing an attacker to exploit a user by re-deploying an application that is signed with original certificate and running the application at a different privilege level. Detail about this new check can be referenced in the following Java documentation: https://www.java.com/en/download/help/java_blocked.xml

3. Select the security tab within the Java Control Panel
4. Select the 'Edit Site List' button
