[ https://issues.apache.org/jira/browse/CLEREZZA-745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13609091#comment-13609091 ]
Minto van der Sluis commented on CLEREZZA-745:

Repeating my initial test still reveals the CME with the following stack trace:

To resolve this issue we probably need to upgrade the Jena dependencies (see also #CLEREZZA-726 )
> ConcurrentModicationException on TDB storage provider (SingleDataset)
> ---------------------------------------------------------------------
>
> Key: CLEREZZA-745
> URL: https://issues.apache.org/jira/browse/CLEREZZA-745
> Project: Clerezza
> Issue Type: Bug
> Reporter: Rupert Westenthaler
>
> 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.
