--- Comment #13 from antonfb@hesiod.org ---
No typo I see.
With my 13.2 freebsd with the jvm set to ipv4stack=false and the sysctl
net.inet6.ip6.v6only set to 0 per the suggested workarounds JDBC was working.
But after upgrade to 14.1 that identical configuration no longer works.
I get bind errors from the JDBC.
I've not found any configuration which lets me run tomcat duel stack and the
postgresql jdbc together. I've had to downgrade and no longer support ipv6 at
all.
This is a serious matter and it looks like nobody cares about this.
Something about FreeBSD's ip address management does not play well with jvms
and this has been a long standing issue.

I'm going to try 15-CURRENT in many configurations, but at this point I may hav
eto give up on freebsd to run my webservices because it there is no jvm which
properly supports ipv6 on freebsd.
