> Application bootstrap.conf configuration has included enabling {{java.net.preferIPv4Stack}} since NIFI-186.
> Although this setting can be changed, advances in IPv6 support across various libraries no longer require this as a default setting.
> The default preference for IPv4 should be removed from bootstrap.conf so that default Java settings will be applied. This setting should be removed for NiFi 2.0 to avoid impacting existing deployments, and new deployments of NiFi 2.0 can still add the setting if needed.
> The Java [Networking Properties|https://docs.oracle.com/javase/8/docs/api/java/net/doc-files/net-properties.html] documentation provides additional background on IPv4 and IPv6 preferences.
