--- Comment #1 from antonfb@hesiod.org ---
As far as I can tell, this is an intended breakage by the freebsd-java
maintainers. If you want duel stack, you must start your java vm with that =
flag
and you must clear the system wide sysctl
net.inet6.ip6.v6only=3D0
IMO I wish this would be reconsidered. This was done five years ago in the =
hope
that dual stack stuff would work via two sockets one for ipv4 and one for v=
6.
But after five years, I don't think that's going to happen.
It would at least be polite to document this and for the maintains to tell
people clearly what the issues are. As far as I can tell, a two line change=
 in
the source code might fix this.
In the meantime, freebsd is just going to be a second rate java platform.
I'll note we don't have jdk23 yet either.
