>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 1.10.0, 1.11.0, 1.11.1, 1.11.4
>         Environment: Windows 10, ubuntu 18.04
>            Reporter: Stefano Piana
>            Priority: Major

> Trying to replace an empty flowfile with and empty value may cause the content repository 
> to accumulate and not being correctly cleaned up until the next NiFi restart.
> this behaviour has been observed on nifi 1.10+
> to reproduce the problem just generate a flowfile that has some content, then replace the content with the ReplaceText processor setting it to always replace and set the replacement to empty string. Copy the ReplaceText processor and try replacing the content with an empty string again, then just use any processor to drain the flowfiles. This will cause the content repository to accumulate and stop being correctly cleaned up.
> here attached a simple flow that reproduces the problem.
