I have configured Wildfly 10 in domain mode.
All configuration of Apache HTTP Sever and mode_cluster are done.
There are 2 hosts. One is master and other is slave.
There are total 4 instances of Wildfly on both hosts, 2 on each hosts.
While executing wildfly on master and slave I am getting a NullPointerException as following:
ERROR [org.jgroups.protocols.UDP] (INT-2,ee,slave1:server-two) JGRP000030: slave1:server-two: failed handling incoming message: java.lang.NullPointerException
Made lot of google but did not find any solution for this.
Why is NullPointerException is there and how can it be rectified ?
Thanks
