> {{HotRodServer.startInternal}} first starts the Netty transport (with {{super.startInternal()}}) and only then initializes the {{clientListenerRegistry}} field. That means the server can accept a request before {{clientListenerRegistry}} is initialized, causing a NPE in {{HotRodDecoder.channelActive()}}.
