>Description:
I have a server which is compiled with WITHOUT_INET6 in src.conf. There is some jails on this server. While jls without switches works fine, with -v switch I got error: "jls: unknown parameter: ip6.addr".

I think jls must omit ip6.addr parameter on systems without IPv6 support and just output the rest of parameters.
>How-To-Repeat:
# echo "WITHOUT_INET6" >> /etc/src.conf
# cd /usr/src && make world
# shutdown -r now
# jls
   JID  IP Address      Hostname                      Path
     3  127.0.0.2       port.jail                     /arc/jail/port
# jls -v
jls: unknown parameter: ip6.addr
