Ignite client nodes are getting terminated when we stop the ignite server.

[jinhwan116]

ThickClient mode is in use. There is an issue where the client terminates when the ignite server is stopped.
The error occurs after the join timeout time has expired.
version : 2.16.0

Even if the server is stopped, can't the client continue to wait without being terminated?
Similar symptoms were seen in the previous issue
https://issues.apache.org/jira/browse/IGNITE-20690
