Hi Chanaka

Looks like this is an incompatibility issue between two clustering

Indeed that might be the issue and I've tested it with WSO2 ESB 4.7.0
with org.apache.axis2.clustering.tribes.TribesClusteringAgent
and it works perfectly. Sadly it won't work on 4.8.0 with (
org.wso2.carbon.core.clustering.hazelcast.HazelcastGroupManagementAgent )
Thank you for your help, much appreciated !
