at java.lang.Thread.run(Unknown Source)解决方法 1
启动配置文件路径：{JMeter 主目录}bin
Linux 启动配置文件：jmeter.sh，添加如下启动参数设置：
export JVM_ARGS="-Djava.net.preferIPv4Stack=true"
Winows 启动配置文件：jmeter.bat，添加如下启动参数设置：
set JVM_ARGS="-Djava.net.preferIPv4Stack=true"
重新启动 JMeter 运行脚本即可解决之前的报错。
解决方法 2
系统配置文件：{JMeter 主目录}binsystem.properties，将 java.net.preferIPv4Stack 设置为 true 即可。
