    I can't help but hope there is a better way to avoid duplicating these 
strings in the code, but it's fine for now.


> UnpackContent cannot unpack any type of flowfile

>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 0.7.0
>            Reporter: Joseph Gresock
>            Assignee: Joseph Gresock

> Two possibly separate problems:
> *Flowfile-stream-v2 and v3*
> This may be a problem with either MergeContent's production of 
> flowfile-stream v2 and v3, or with UnpackContent's inability to unpack them, 
> not sure which.  Here is a screen shot with how to reproduce it: 
> https://ibin.co/2sCwqbFbAs3a.png
> Essentially, when you pack a flow file as flowfile-stream v2 or v3, a 
> subsequent UnpackContent set to the respective type fails with the error 
> "Cannot unpack {} because it does not appear to have any entries".
> *Flowfile-tar-v1*
> When selecting flowfile-tar-v1 from UnpackContent, you immediately get 
> @OnScheduled error failure as soon as you start the processor, which prevents 
> it from processing any incoming flow files.  Here is a screenshot:
