Subject: openjdk-6-jre: cannot open socket to localhost

Date: Sat, 13 Mar 2010 15:12:48 +0000

[Message part 1 (text/plain, inline)]

Package: openjdk-6-jre
Version: 6b18~pre2-1
Severity: important

Latest update breaks the ability to open a socket to 127.0.0.1, unless
-Djava.net.preferIPv4Stack=true is set. Test code attached, which assumes there
is a service listening on port 80.

also, screwing with net.ipv6.bindv6only (as per #560056) has no effect

Opening Socket from 31000 to 80
