> As the maintenance tasks run asynchronously, the used services might get deactivated while the maintenance task is running. Although the task itself checks the configuration object for being valid, it does not check any service it accesses. This might run in an NPE.
> While the NPE itself should not pose a problem, it's not the best way to stop a maintenance task
