[keycloak-user] How to enable Infinispan cache for realms, users and user sessions in Keycloak 1.6.1?

[Lohitha Chiranjeewa]

Hi,

We're in the process of assessing the impact on upgrading from Keycloak
1.2.0 to 1.6.1. We came across an issue when trying to enable Infinispan
cache through the keycloak-server.json file as we used to do in 1.2.0.

We have the following entries in 1.6.1:
    "realm": {
        "provider": "infinispan"
    },

    "user": {
        "provider": "infinispan"
    },

    "userSessionPersister": {
        "provider": "infinispan"
    },
.........
    "connectionsInfinispan": {
        "default" : {
            "cacheContainer" : "java:comp/env/infinispan/Keycloak"
        }
    }

All configurations in 1.6.1 standalone-ha.xml file remains comparable (and
correct to the best of our knowledge) with the ones in 1.2.0.

With the above configs, when we start the Keycloak service the following
error(s) get logged:

Is the new way to enable Infinispan different to what we had earlier? If
so, can someone please point out the correct way?
