unknown code for readObject at 0x45 (E)

之前可以正常使用，后来引入dubbo 2.5.3，将一些基础服务剥离出去后，再由调度任务调用执行器时，出现以上异常，也可能不是dubbo引起的异常，摸不着解决方案，请教作者

dubbo相关的配置

跟踪代码显示： HttpClientUtil.postRequest() 方法
HttpResponse response = httpClient.execute(httpPost);

HttpResponseProxy{HTTP/1.1 500 Server Error [Connection: close, Server: Jetty(8.2.0.v20160908)] ResponseEntityProxy{[Chunked: false]}}

求教

你在执行器测debug调试下，看到了 “HTTP/1.1 500 Server Error ” 好像执行器被改坏了

@xuxueli 执行器是debug模式启动的，调度器在调用的时候请求还没到执行器的断点就抛出异常了。

我换成默认的执行器测试了一下，确实可以调用成功。
