Bela Ban commented on JGRP-1878:
--------------------------------

I know. But looking at the options available with {{setSocketOption()}}, {{IP_MULTICAST_ALL}} is *not* among them, even in JDK 8.

> Multicast discovery does not work on JDK8 when using different bind IP addresses. This blocks EAP certification on JDK8.
> Steps to reproduce with draw, switch to JDK8:
> {noformat}
> export IP_ADDR=127.0.0.1
> ./draw.sh
> export IP_ADDR=192.168.1.10
> ./draw.sh
> {noformat}
> Everything works when binding to the same IP address or using JDK 6 or 7. Possibly a JDK8 bug..
