> Node states sometimes refer to more than a single generation of segments
> after a full compaction

> Key: OAK-8033
> URL: https://issues.apache.org/jira/browse/OAK-8033
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Affects Versions: 1.10.0, 1.8.10, 1.6.16, 1.8.11, 1.10
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Priority: Major
> Labels: TarMK, candidate_oak_1_6
> Fix For: 1.12.0, 1.6.17, 1.10.1, 1.8.12
>
>
> Due to a regression introduced with OAK-7867 a full compaction can sometimes
> cause nodes that are written concurrently to reference segments from more
> than a single gc generation.
> This happens when the {{borrowWriter}} method needs to [create a new
> writer|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-segment-tar/src/main/java/org/apache/jackrabbit/oak/segment/SegmentBufferWriterPool.java#L197-L201].
> In this case the new writer will be of the generation of the current head
> state instead of the generation associated with the current write operation
> in progress.
