> Key: OAK-12034
> URL: https://issues.apache.org/jira/browse/OAK-12034
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Reporter: Nuno Santos
> Priority: Minor
> Fix For: 1.90.0
>
>
> Reported by [~mreutegg]
> "The implementation first checks if the segment is present in the persistent
> cache. This is actually not correct. A segment may be present in the cache,
> but that doesn't mean the segment belongs to the archive this reader is based
> on. All archive reader implementations also keep an in-memory index of
> segments they contain. That is, calling delegate.containsSegment() should be
> cheaper and not involve I/O."
