org.apache.nifi.processor.util.FlowFileSessionWrapper deprecated

[Russell Bateman]

We're moving our code base ahead from NiFi 1.0.0 to 1.1.2 and have some 
classes that are using FlowFileSessionWrapper. Appears to wrap up a 
flowfile and its corresponding session; our use was in some special 
batching code. I could roll my own, I guess, but there may be a very 
good reason not to, i.e.: a better way to handle what it did for us, 
stay out of trouble, etc.

So far, Googling encourages me to believe that this has been deprecated 
and I shouldn't use it, but so far I haven't stumbled upon why or what 
to do differently. Can anyone throw some light on this?

Thanks.
