Ich versuche, netty per Clojure zu benutzen. Ich kann den Server starten, er kann jedoch keinen akzeptierten Socket initialisieren. Unten finden Sie die Fehlermeldung bzw. den Code. Weiß jemand, was falsch ist / oder sein könnte? Ich glaube, das Problem ist mit(Channels/pipeline (server-handler)) Vielen Dank.

Fehlermeldung
