What to do with unknown .jar files?

So Comodo blocks/sandboxes unknown .jar files.

They don’t process .jar applications in this forum, so… am I expected to take a guess if I trust them, or is Comodo able to provide a way to know if they are safe or not?

Kind regards,

Realtime Scan and Archive File Extensions option?

I use Comodo Firewall.

This is to do with the HIPS/Auto-Containment module not the Firewall module. Which is why I posted it in the HIPS/Auto-Containment forum.
