Bulk close for 1.7.7
> SegmentWriteOperation.isOldGeneration() too eager

> Key: OAK-6601
> URL: https://issues.apache.org/jira/browse/OAK-6601
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Labels: compaction, gc
> Fix For: 1.8, 1.7.7
>
>
> The {{SegmentWriteOperation.isOldGeneration()}} predicate includes some
> segments that are not "old". This leads to more deferred compaction
> operations than strictly necessary. The affected segments are those generated
> by tail compaction. Tail compaction created segments should only be included
> in the predicate once they are from another full compaction operation.
> Otherwise referencing such segments is fine as they will not be reclaimed in
> a cleanup following a tail compaction.
