【问题描述】：

这个问题已经有了答案here。

从过去几天开始，我正在与jmeter 合作。它运行良好。

但是今天当我尝试使用http 脚本记录器录制新脚本时，当我点击开始时，我遇到了异常..

java.io.IOException:   >> keytool error: java.lang.RuntimeException: java.io.IOException: DNSName components must begin with a letter <<
Command failed, code: 1

【解决方案1】：

这可能是由于bug in Java 造成的，因为有很多域以数字开头，例如

所以选项在：

查找不受影响的Java 版本，即JDK 8 u 151
使用替代录制解决方案，例如JMeter Chrome Extension

【讨论】：

另一种选择是将jmeter升级到5.1或更高版本，jmeter解决了这个问题。
