> It seems that the mvstore wasn't shut down properly during the stop of the
> DocumentNodeStore. For me it seems that the DocumentNodeStore doesn't use the
> persistent cache anymore until there was a "hard" restart (on the JVM).
> It would be good if even in this situation the shutdown of the
> DocumentNodeStore could drop the lock on the mvstore, so a clean restart of
> the bundle is possible.
