>          Issue Type: Bug
>          Components: core, mongomk, rdbmk
>    Affects Versions: 1.0.21, 1.3.6, 1.2.6

> Scenario (test case will follow):
> 1) service configured for RDBDocumentStore with DataSources
> 2) gets started
> 3) DataSource unregisters, DocumentNodeStore gets shut down
> 4) DataSource is registered again
> 5) restart of DocumentNodeStore fails with NPE because at least one required component (executor?) now is null
> We need to decide whether this is a scenario that should be supported or not. If yes, we need to fix it. If no, we need to make the code more robust and improve diagnostics.
