[infinispan-issues] [Red Hat JIRA] (ISPN-11567) Scattered caches with a single node expire entries immediately

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: 10.1.5.Final, 11.0.0.Dev03 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.1.0.Final {{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.
