Bela Ban commented on JGRP-2344:
--------------------------------

Although I switched to GraalVM 19, there were still issues around MulticastSockets:

SEVERE: JGRP000017: belasmac-23297: disconnect failed: java.lang.NullPointerException
{noformat}

Apparently, MulticastSocket.joinGroup() doesn't work.

Other issues when option {{-J-Djava.net.preferIPv4Stack=true}} is *not* enabled when the native image is created:
* MulticastSocket.setInterface()/setNetworkInterface() fails
* MulticastSocket.setTimeToLive() fails (see below)
