> Key: DERBY-6313
> URL: https://issues.apache.org/jira/browse/DERBY-6313
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.11.0.0
> Environment: Derby trunk, revision 1515737
> java version "1.8.0-ea"
> Java(TM) SE Runtime Environment (build 1.8.0-ea-b103)
> Java HotSpot(TM) 64-Bit Server VM (build 25.0-b45, mixed mode)
> Oracle Linux Server release 6.4
> Reporter: Knut Anders Hatlen
>
> I saw this diff when running derbyall against trunk:
> ********* Diff file storeall/storemore/OnlineBackupTest1.diff

> It may be related to DERBY-973, but it is different in that it happens in the
> DML thread that runs in parallel with the online backup. The failure reported
> in DERBY-973 happens later, during restore of the backed up database.
