Firewall throws error "no code signature" at new Java Installer.

My software firewall sees new Java Installers as suspicious. I just bypassed the error message, and installed the new version, again. This is a recent problem. Does anyone know if there is a way to verify the installer when this happens? Should I chuck the automated installer and go directly to Oracle for a download of the installer?

Thanks in advance for any thoughts anyone has.

Your question has nothing to do with LibreOffice. Ask your firewall’s vendor why it behaves this way.
