• 分析
  1.最开始百度到的解决办法是修改jmeter.bat中配置的堆内存等大小，修改后重启依然报错。
  2.后来发现，Jmeter非常的友好，将关于报错的更多详细内容都记录到了bin目录下一个叫hs_err_pid***.log的日志中，里边记录了SYSTEM,THREAD,PROCESS等非常详细的信息，其实详细的东西我也不能完全看懂，但是看到了环境变量的时候，我发现CLASSPATH的值有点不对劲，我的是“CLASSPATH=,;D:\jdk1.8.0_92_64bit\lib;D:\jdk1.8.0_92_64bit\lib\tools.jar”，就这等于号后边的“,;”是什么鬼？
  3.果断修改环境变量中的CLASSPATH，去掉扎眼的“,;”，之后重启Jmeter

• 结果
  酱酱~搞定！
