多 JDK 导致 jmeter 无法保存的解决办法

今天在使用 jmeter 的时候发现怎么也保存不了也保存不了新的项目，我就很奇怪啊。之前一直好好的为啥突然不行了。我的日志查看面板里面一个大大的报错引起了我的注意

// 软件日志返回的

跟这篇文章说的挺像，虽然不是一个软件报的错误 https://bugs.eclipse.org/bugs/show_bug.cgi?id=482318 。总体来说就是因为这软件调用了内部类随时可能因为 jdk 等级而不能用。我现在的等级是 jdk17 所以需要降级，但电脑的 JAVA_HOME 不能动只能着手修改 jmeter 的启动脚本,在 jmeter.bat 中添加以下内容

rem Minimal version to run JMeter
set MINIMAL_VERSION=1.8.0
rem 在此行下面添加以下内容
rem 填写 JDK 11 或者 8 的路径，例如 C:\Program Files (x86)\Java\jdk-11.0.10
set JAVA_HOME= C:\Program Files (x86)\Java\jdk-11.0.10
set PATH=%JAVA_HOME%\bin;%PATH%

双击运行，这时候再点保存按钮就成功的展示选择界面了。
