> Ensure Caffeine cache does not return stale entries
> ---------------------------------------------------
>
> Key: CASSANDRA-15153
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15153
> Project: Cassandra
> Issue Type: Bug
> Components: Feature/Authorization
> Reporter: Per Otterström
> Assignee: Aleksei Zotov
> Priority: Normal
> Labels: security
> Fix For: 4.0.2, 4.1
>
>
> Version 2.3.5 of the Caffeine cache that we're using in various places can
> hand out stale entries in some cases. This seem to happen when an update
> fails repeatedly, in which case Caffeine may return a previously loaded
> value. For instance, the AuthCache may hand out permissions even though the
> reload operation is failing, see CASSANDRA-15041.
