Description

If NiFi fails to start up successfully, the act of attempting to shut down appears to result in a duplicate FlowController instantiation. A symptom of this is initializing the flow file repo twice which fails with an overlapping file lock exception.

The actual reason that start up failed is logged further back in the app log.
