Customer reported an issue about Coherence node member could not join coherence cluster. When customer tried to start a jmx node in the cluster, found the member is failing on startup. Customer did check the RemainingMemberSet in the senior node of the cluster and JMX node and then shutdown all nodes listed in the RemainingMemberSet list, but even then jmx node can't join the cluster, so customer finally shutdown node one by one and then tried whether it can restart again. However, until a particular member/node was restarted jmx member did not join the cluster. The member/node that was halted the jmx node start was a node it's Management service start was failed as its thread dump did not have the Invocation:Management & Invocation:Management:EventDispatcher threads.
