[keycloak-user] Distributed Keycloak user sessions using Infinispan

Some more information -
Quick summary - I'm trying to test HA of Keycloak user sessions when one of the nodes goes down, users should not have to login again as their session information would be available on other node. Keycloak cluster is setup to store users session on Infinispan (testing using distributed-cache and replicated-cache).
To see the cache information on Keycloak nodes, I setup hawtio on these node. Initial state of caches on both the nodes are captured in these images (see 110.DC.Start.png and 111.DC.Start.png)
Then user logs into server 111. We can see the session entry value increasing (see 111.DC.Login.On.111.PNG). When we look at session entry on 110 server, we see that the count has increased there too. That means that they session is being successfully replicated (see 110.DC.Login.On.111.PNG).
To verify if this works other way around, we logged into server 110, and its session entry count increased (see 110.DC.Login.On.110.And.111.PNG). When we check 111, we can see that session entry count increased on this server too. (see 111.DC.Login.On.110.And.111.png).
We initially suspected that our sessions were not getting replicated. Using hawtio, we can see session entry count increasing on both servers. Could this mean that there is a bug in Keycloak's code while fetching user sessions? Is there any other way we can validate user sessions?

Looks like the servers are talking to each other (setup on unicast) and session cache between the servers are shared, but we still cannot successfully fetch user info when token is generated by one server (test-server-110) and data from another (test-server-111).
Any suggestions/debugging approaches appreciated.
