This is a symptom of a bug in sun's java6 regarding ipv6.

Try
$ /sbin/sysctl net.ipv6.bindv6only

If this value is 1 you need to disable the setting:

$ sudo /sbin/sysctl net.ipv6.bindv6only=0

For a persistent fix:
Check /etc/sysctl.conf and /etc/sysctl.d/* for this setting and restart procfs after changing it.

If this was your problem, you should have networking back :)

Cheers.
