[JBoss JIRA] (ISPN-6857) OutdatedTopologyException in clustered invalidation cache because StateTransferInterceptor not in the chain
by Tristan Tarrant (JIRA)
[ https://issues.jboss.org/browse/ISPN-6857?page=com.atlassian.jira.plugin.... ]
Tristan Tarrant commented on ISPN-6857:
---------------------------------------
An Invalidation cache doesn't transfer state, only invalidations, so the "missing" StateTransferInterceptor is not a mistake. However the analysis is correct, the remove should be retried.
