> NiFi is always loading a specific version of httpcore to classpath
> ------------------------------------------------------------------
>
> Key: NIFI-2034
> URL: https://issues.apache.org/jira/browse/NIFI-2034
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 0.5.1, 0.6.1
> Reporter: asanka sanjaya
>
> We have written a custom nifi processor to connect to microsoft exchange
> server and get emails. It runs perfectly as a standalone application. But
> nifi always loads httpcore-4.4.1.jar and httpclient-4.4.1.jar to classpath
> even though the nar file contains httpcore-4.4.4.jar and httpclient-4.5.2.jar.
> Because of that, it throws this error.
