> The consequence of this is that if the framework throws a 
> FlowFileAccessException, for example, the Processor is catching that and then 
> routing to failure, when the framework should be able to catch it and roll 
> back the ProcessSession.  Specifically, we are seeing this because on of the 
> content repository containers ran out of disk space and files were then 
> routed to 'failure'. Instead, the session should have been rolled back and 
> the FlowFile processed again.
