The following exception is thrown when a cluster of two nodes is created on the same virtual host with DXM 7.1.1
"javax.management.InstanceNotFoundException: JGroupsReplication:type=protocol,cluster="ehcache-jahia",protocol=GMS"
The file.node.properties shouldn't contain placeholders.
In jahia.node.properties, the cluster.activated variable was set as below:
cluster.activated = ${jahia.cluster.activated}
This is not allowed.
The solution is to set the setenv.sh script as below:
CATALINA_OPTS="$CATALINA_OPTS -DjahiaConfig.cluster.activated=true"
