> As of NIFI-5757, SQLExceptions in PutDatabaseRecord's code to determine table 
> information have been wrapped in a ProcessException as the code was moved 
> into a lambda. Until NIFI-8146, this introduced a regression as the flowfile 
> would be rolled back (even if Rollback on Failure is false) rather than being 
> routed to failure.
> The refactor of PutDatabaseRecord in NIFI-8146 changed the logic to correctly 
> route to failure; however the exception is still wrapped in a 
> ProcessException and should be unwrapped before logging. Behavior (transfer 
> to failure) should remain the same and thus avoid another regression.
> To test, simply send a flowfile to PutDatabaseRecord to a table that doesn't 
> exist. In NiFi 1.8, it will be routed to failure. In NiFi 1.9-1.12, it will 
> be rolled back. In 1.13+ it is again routed to failure. After this Jira, it 
> should still be routed to failure but logged as a SQLException rather than a 
> ProcessException with a SQLException cause.
