I am trying to upgrade Cassandra 3.11.13 cluster to 4.1.3, and during the
upgrade observed following Exception on 3.11.x nodes.

There is a difference between the ApplicationStates Enum in between 3.11 & 4.1,
with the former containing 25 states only. However, I think that padding state
shouldn't be used by the 4.1 during gossip exchange. This only happens when a
Gossip is initiated by a 4.1 node to a 3.11 node, and 3.11 fails to send a
GOSSIP_DIGEST_ACK.
