と春ブーツで、次のAHC-WSの定義実行時に
.........
.multicast()
.parallelProcessing()
.pipeline()
.marshal().json(JsonLibrary.Jackson)
.convertBodyTo(String.class) // Avoids string serialization issues in websocket component.
.to("ahc-ws://localhost:8080/votes?sendToAll=true")
.end()
.........
を使用してこれにパブリッシュするとき、私は次のエラーを取得しますシンク

何が起こっているか/紛失していると思いますか？
私は、netty-all（下を見てください）が4.1.5であり、他のすべてのnetty依存関係が4.0.41であるという点で、依存ツリーが少し奇妙であることに気付きました。これが「Gradleの依存関係」で生成された
