Bug#618725: no idea where "Sun Java Control Panel" is

[jidanni at jidanni.org]

I had success hacking /etc/sysctl.d/bindv6only.conf .
I have no idea how to get to any
"Sun Java Control Panel -> Java -> View -> User -> Runtime Paremeters"
that you are talking about. And even if I did, I have to make this
change to several computers, so you had better tell me what file to stick the
"-Djava.net.preferIPv4Stack=true"
into, so I can propagate the file instead of having to play with some
interactive thing.
