> Key: CLEREZZA-745
> URL: https://issues.apache.org/jira/browse/CLEREZZA-745
> Project: Clerezza
> Issue Type: Bug
> Reporter: Rupert Westenthaler
> Priority: Major
>
> As reported by Minto van der Sluis in [1] the SingleDataset Jena TDB
> TcProvider can throw .ConcurrentModificationException when iterating over a
> read protected MGraph and a modification is done to an other graph managed in
> the same Jena TDB Dataset. This includes creating a new graph in the dataset.
> Based on a first analysis this is caused by the Single Dataset Jena TDB
> TcProvider using per TripleCollections ReadWrite Locks instead of a single
> ReadWrite Lock for all graphs managed by the same Jena TDB Dataset.
