> When setting {{-bind_addr}} to localhost (either 127.0.0.1 or ::1) without specifying {{-Djava.net.preferIPv4Stack=true}}, JGroups fail to connect. The following errors are logged:

> {code}
> I'm not sure if there's some other configuration option that I forgot to add, but the example (in Steps to Reproduce) works with previous versions (3.6.6 for example), so I assume not.
