Subject: [infinispan-dev] JGroups Error: JGRP000029 observed with "JGroups 3.6.8 + Infinispan 8.2.2":

Hi Bela Ban,

We have been trying to use JGroups 3.6.8 with Infinispan 8.2.2., in this context we are observing an issue with the Replication Mode of Infinispan usage.
We see the below exception from Jgroups:
JGRP000029: failed sending message to <>:7800 (100 bytes): java.lang.NullPointerException, headers: TCPGOSSIP: [type=GET_MBRS_REQ, cluster=x-cluster], TP: [cluster_name=x-cluster]

The configurations used are highlighted below:

Infinispan config

<infinispan>

    <jgroups>

        <stack-file name="configurationFile" path="config/jgroups.xml"/>

    </jgroups>

    <cache-container>

        <transport cluster="x-cluster" stack="configurationFile" />

<replicated-cache name="transactional-type" mode="SYNC">

            <transaction mode="NON_XA"  locking="OPTIMISTIC" transaction-manager-lookup="org.infinispan.transaction.lookup.JBossStandaloneJTAManagerLookup" auto-commit="true"  />

<locking acquire-timeout="60000"/>

<expiration lifespan="43200000"/>

        </replicated-cache>

    </cache-container>

</infinispan>

 

Jgroups configuration

<!--

    TCP based stack, with flow control and message bundling. This is usually used when IP

    multicasting cannot be used in a network, e.g. because it is disabled (routers discard multicast).

    Note that TCP.bind_addr and TCPPING.initial_hosts should be set, possibly via system properties, e.g.

    -Djgroups.bind_addr=192.168.5.2 and -Djgroups.tcpping.initial_hosts=192.168.5.2[7800]".
