Server 1 -> Let's say IP is X. Status is running.
Server 2 -> Let's say IP is Y. Status is not running. We stopped this node
for various reasons.
Client1 -> TcpDiscoveryVmIpFinder ipAddress list has two server IPs - X,Y
Client 2 -> TcpDiscoveryVmIpFinder ipAddress list has two server IPs - X,Y
When we start Client1, and Client 2 App machines both at a time. In Client2
App machine, we found the following thread trace. A thread is kept waiting
here since that App started.

Can someone tell why it is WAITING here in Client2? In Client1 there were no
issues and everything is working fine. All the threads in Client2 are in
waiting state as "IgniteConnectionHandler" class's static block code is not
completed.
