Issue for starting Tomcat app server



During app server startup, JVM reaches to the point where it is actioning Hazelcast clustering and then it just hangs and does not proceed.

Steps to Reproduce

  1. Bring down all JVMs.
  2. Truncate the pr_sys_statusnodes table and restart the system. It hangs on the statement "This node is starting first".
