DbDataStore: garbage collection deadlock
----------------------------------------

                 Key: JCR-2026
                 URL: https://issues.apache.org/jira/browse/JCR-2026
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller
            Priority: Minor


Sometimes, the unit tests hangs with the following threads blocked. It looks like a database
level deadlock caused by the DbDataStore implementation. The database used is Apache Derby.
