我在使用Mac上的VisualVM时遇到了一些麻烦。
每当我运行visualvm应用程序时（从安装的应用程序或通过转到/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/bin/jvisualvm（unix可执行文件），它会打开终端，有一会儿，visualvm也会启动，然后在终端打印以下内容并且visualvm关闭

I have recently upgraded from Sierra to High Sierra. I think I have used visualvm before this upgrade, might be once or twice though.
Any help to resolve this issue would be great..!! Please let me know if any additional information is needed.
I tried to use
/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/bin/jvisualvm -J-Dnetbeans.logger.console=true but got the following error. Guess this is because I don't have netbeans installed??

我还能注意到visualvm脚本调用了nbexec文件。当我尝试独立运行时，我在控制台上收到了以下错误。
