> On error, the Livy UI shows verbose output on error pages including the Jetty
> version number. This could be considered as a security vulnerability. We can
> make it configurable and avoid sending server version details.
> The Jetty version is there in every response header as well:
> {noformat}
> $ curl -v $LIVY_URL/sessions
> ...
> < Server: Jetty(9.4.43.v20210629){noformat}
