Description

When using a ListFTP processor with proxy configured it might happen that the instance running NiFi can't resolve the destination host name. This should be ok as it's enough for the proxy to be able to resolve it.
But NiFi tries to resolve the hostname (see [1]) that leads to an UnknownHostException.
