版本：1.3.8 单笔运行的时候发现一直返回null，开了JMeter日志，抛了如下日志，请问跟这有关系么？

2020-09-10 11:24:24,524 DEBUG c.a.d.c.e.ExtensionLoader: [DUBBO] package com.alibaba.dubbo.remoting; import com.alibaba.dubbo.common.extension.ExtensionLoader; public class Dispatcher$Adaptive implements com.alibaba.dubbo.remoting.Dispatcher { public com.alibaba.dubbo.remoting.ChannelHandler dispatch(com.alibaba.dubbo.remoting.ChannelHandler arg0, com.alibaba.dubbo.common.URL arg1) { if (arg1 == null) throw new IllegalArgumentException("url == null"); com.alibaba.dubbo.common.URL url = arg1; String extName = url.getParameter("dispatcher", url.getParameter("dispather", url.getParameter("channel.handler", "all"))); if(extName == null) throw new IllegalStateException("Fail to get extension(com.alibaba.dubbo.remoting.Dispatcher) name from url(" + url.toString() + ") use keys([dispatcher, dispather, channel.handler])"); com.alibaba.dubbo.remoting.Dispatcher extension = (com.alibaba.dubbo.remoting.Dispatcher)ExtensionLoader.getExtensionLoader(com.alibaba.dubbo.remoting.Dispatcher.class).getExtension(extName); return extension.dispatch(arg0, arg1); } }, dubbo version: 1.3.8-jar-with-dependencies, current host: 192.1.160.10

另外还有就是大量类似下面的记录
