Java 驼峰网络组件：未能创建选择器

我试图使用netty从tcp套接字中消耗字节。我正在使用ApacheCamel 2.12.1、SpringDSL和Windows。我的路线很简单：

<camelContext xmlns="http://camel.apache.org/schema/spring" autoStartup="true">
    <route id="my-route">
        <from uri="netty:tcp://127.0.0.1:4102?sync=true&amp;textline=true" />
        <convertBodyTo type="java.lang.String" />
        <to uri="file:./data" />
    </route>
</camelContext>

我在启动路线时遇到此异常：

有没有关于它还没有开始的想法？谢谢

NoSuchMethodError

通常是由于

类路径上有不兼容的jar（太旧或太新）造成的

（我偶尔发现免费的JBoss Tattletale对于识别挂在我的
类路径上的类或jar的旧副本很有用。但是，这里可能没有复制的问题。）
我不确定它是否与java.lang.NoSuchMethodError有关：org.JBoss.netty.channel.socket.nio.SelectorUtil.open（）Ljava/nio/channels/Selector；是的。NoSuchMethodError总是由不兼容的jar引起的。如果你不相信我，谷歌一下。我发现了问题所在。Camel Zookeeper和Camel Netty包含了Netty库的不同版本，api中似乎有变化，Camel正在寻找一种根本不存在的方法。因此，最后它是一个不兼容的jarI将检查我们是否可以让骆驼动物园管理员和骆驼netty使用相同版本的netty。我刚刚在camel中填充了一个JIRA并为其应用了补丁。
