> Hi team,
> Using 1.13.2 and running a pipeline pulling down a bunch of ZIP files, and noticed a regression in behaviour between my two environments. 
> The 1.12.1 instance (running on RHEL) was able to unpack the file successfully, whereas the 1.13.2 instance complains of an error stating 
> {code:java}
> 2021-03-23 04:12:39,361 ERROR [Timer-Driven Process Thread-8] o.a.n.processors.standard.UnpackContent UnpackContent[id=5d0fda44-0178-1000-872e-6c183c633c89] Unable to unpack StandardFlowFileRecord[uuid=9fa7650e-8557-465c-b39b-0e9b5e25ee0a,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1616471834548-154, container=default, section=154], offset=0, length=11095546],offset=0,name=3b70dbf9-b0a1-4d63-b2fd-0efe2a7291b8,size=11095546] because it does not appear to have any entries; routing to failure{code}
> The only discernable difference between this file and files that were able to be unpacked was that the offending files have
>  * a "compression method" of Deflate:Maximum (as opposed to Deflate on the working files)
>  * an "offset" of 4 (as opposed to "0" on the working files)
> See attached for the template I used for testing the same functionality on my 1.13.2 and 1.12.1 NiFi instances. I've downgraded the Ubuntu instance to 1.12.1 and noted that the UnpackContent processor functions as expected, so I don't believe it's an issue with the host OS. 
> I'm not sure whether the issue introduced in 1.13.1 might also have impacted this, with the offset, or if it's something to do with the compression method, or something else entirely.
> Happy to provide further detail if needed :)
> Cheers,
> Tom
