This is where I got to (almost) - but it doesn't seem to make any 
difference.

I have tomcat55_java_opts="-Djava.net.preferIPv4Stack=true" in rc.conf.

When that didn't work I tried taking INET6 out of the kernel completely.

Then I took all ipv6 references out of the hosts file (I'm getting 
desperate, you can see).

I still consistently get the following in the logs (everything starts 
fine until this point).

SEVERE: StandardServer.await: create[8005]:

There are definitely no services running on that port (netstat 
confirms...) and the error seems consistent with other encountering the 
ipv6 problems.

I'm not sure what I'm doing wrong, but I'm prepared to accept that it's 
something dumb.
