There is a still unsettled debate AFAIK about the correct (as in RFC-compliant) behavior in respect to IPv4 mapped address usage, which in turn reflects on the default setting of the sysctl knob. The IETF recommendation is supposed to be changing, so things are a bit in a flux. On the positive side, there was a suggested fix for this on the list a while ago, see: http://lists.freebsd.org/pipermail/freebsd-java/2003-November/001215.html Perhaps this will DTRT always.
