Missing required permissions manifest attribute in main jar

When I updated java to the latest security fix, I got this error message:

"Missing required permissions manifest attribute in main jar"

The solution in my case was to add the URL I tried to access to Java Exception Site list.

On MAC open system preferences, click on Java and a new window opens up. Click the security tab and press Edit Site list.

Restart the web browser just in case and try to access the site again.
