> Key: OAK-6520
> URL: https://issues.apache.org/jira/browse/OAK-6520
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Labels: compaction, gc
> Fix For: 1.8, 1.7.7

>
> This is a follow up to OAK-3349: in tail compaction the {{FileStore.GarbageCollector.getBase()}} might fail to determine the base state to rebase onto. In this case we should fall back to full compaction and report (log, JMX) the problem and its exact cause.
> Failing to determine the base state might be caused by a missing or invalid {{gc.log}} file or a invalid or missing record id for the base state being recorded in {{gc.log}}. None of these cases should impact system stability.
