Java 插件11.211.2.12 x86_64
使用 JRE 版本 1.8.0_211-b12 Java HotSpot(TM) 64-Bit Server VM
用户主目录 = /Users/danni
16:21:12 java.security.AccessControlException: access denied ("java.util.PropertyPermission" "user.home" "read")
	at java.security.AccessControlContext.checkPermission(AccessControlContext.java:472)
16:21:12 [api] notify javascript applet unauthorized or jre unsupported.

cd /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre/lib/security
sudo vi java.policy
        permission java.util.PropertyPermission "user.home", "read";

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

以上两个都不是，Jre终于找到:

• /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security
• https://includestdio.com/1346.html
• 增长permission java.util.PropertyPermission "user.home", "read";解决。
