标题: Jmeter 工具
1、线程组设置：
线程数为：1
线程循环次数：2
2、添加 java Sampler
3、开始执行
结果，显示：

我设置运行了，没遇到这样的错。楼主要不把jmx文件贴出来看看吧

楼主，可以问下这个问题你怎么解决的不？我设置成运行1次时，没报错。设置成循环多次，就会抛这个错误~~

这个问题是由于你写的java脚本中，sr = new SampleResult(); 实例化位置没放对，我放入了初始化里面了，放在run里就正常了

您确定这样就能解决问题吗？我是定义成成员变量，然后在runtest方法里初始化的，为啥还是报这个错？

dos.close();
br.close();
socket.close();

} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();

}

return results;
} 看下我的代码

请问你设置多线程循环时下面错误是怎么解决的
