can close this issue.

> Project: Kafka
> Issue Type: Bug
> Reporter: Mayuresh Gharat

> Consider this scenario :
> 1) We have a Kafka Broker running on PlainText and SSL port simultaneously.
> 2) We try to plugin a custom principal builder using the config
> "principal.builder.class" for the request coming over the SSL port.
> 3) The ChannelBuilders.createPrincipalBuilder(configs) first checks if a
> config "principal.builder.class" is specified in the passed in configs and
> tries to use that even when it is building the instance of PrincipalBuilder
> for the PlainText port, when that custom principal class is only menat for
> SSL port.
> IMO, having a DefaultPrincipalBuilder for PalinText port should be fine.
