[keycloak-user] Update from 1.8.1 to 1.9.2: Persistent sessions fail to load

[Marek Posolda]

We don't support (and never tested) the setup, which is using infinispan 
file-store to store the infinispan user/client sessions by infinispan.

Are you using offline sessions? If so, you don't need to configure 
infinispan store. Keycloak takes care of persisting offline user/client 
sessions into it's database and restore them automatically to infinispan 
at next startup. We plan to add support for optionally persist 
non-offline user/client sessions too to have them "survive" server 
restart. But it's not yet supported ATM.

So for now, I suggest you manually delete the file where are infinispan 
sessions stored.
