Package: openjdk-6-jdk
Version: 6b16-1.6.1-2
Severity: important

Netbase has recently introduced the sysctl-setting
net.ipv6.bindv6only=1 in /etc/sysctl.d/bindv6only.conf and this setting
will probably be the default in squeeze.

This setting breaks networking in java, and any traffic will for openjdk
always result in a "java.net.NoRouteToHostException: Network is
unreachable".

It should probably be an rc-bug, but setting as important for now, since
users can easily rectify the issue.

Quick fix for users hit by this:

sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' \
/etc/sysctl.d/bindv6only.conf && sudo invoke-rc.d procps restart


This is present in both Sun's Java6 and OpenJDK6.

cheers, 
Heikki
