Java 使用-Verbose进行详细日志记录：类不适用于Tomcat 9和JDK11

我将Tomcat9与Oracle JDK8一起使用。对于已加载类的日志记录，我喜欢使用开关

-verbose:class

，它在JDK8下工作正常，但在JDK11下不输出任何内容

我已经在Windows 10上安装了Tomcat 9作为名为“Tomcat9”的服务，因此我使用了

/bin/Tomcat9w.exe

上的属性面板进行配置

现在，在Java选项文本字段的Java选项卡下，我将使用

-verbose:class

来启用加载类的日志记录，这些类将显示在stdout日志中的

/logs/tomcat9 stdout.xxxx xx.log

。 如果仍然在Java选项卡上，我将Java虚拟机字段中使用的JVM更改为Java 11版本，则所提到的verbose命令将停止工作。更新的统一日志命令，如

-Xlog:class+load=info，class+unload=info

也不起作用。这已经通过Oracle和Amazon的Coretto JDK11实现进行了测试

完全没有关于这个问题的任何信息表明，真正的问题完全存在于其他地方，我很可能在这里提出了错误的问题。但现在，我只知道这些。如果缺少什么，请告诉我

提前谢谢
