-----------------------------------

             Summary: Scattered caches with a single node expire entries immediately
                 Key: ISPN-11567
                 URL: https://issues.redhat.com/browse/ISPN-11567
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 11.0.0.Dev03, 10.1.5.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 11.0.0.Dev04


{{ClusterExpirationManager.checkExpiredMaxIdle()}} sends a {{TouchCommand}} to the other owners and expires the entry locally if the touch was unsuccessful.

{{ScatteredTouchResponseCollector}} is stateless, and reports that the entry has not been touched if it doesn't receive any {{true}} response. However, this is only correct if at least one backup entry existing on another node, and that is not the always the case: e.g. between the backup node leaving the cluster and another node becoming a backup, or when the cluster has a single node.

Since {{ClusterExpirationManager.checkExpiredMaxIdle()}} is called on every read, before the entry being expired on the local node, it means a transient entry in a scattered cache with a single node will expire on the first read, immediately after being inserted.
