在 jvisulavm 中添加 JMXConnection 时出现 java.lang.SecurityException

Question

各位开发人员大家好，

我尝试使用 jvisualvm 打开与应用程序的 jmx 连接，但是当我添加连接时，它失败并出现 SecurityException。谁能帮我弄清楚如何避免这种情况？

感谢任何帮助。

您的应用代码中是否有 SecurityManager？

@Override
public PermissionCollection getPermissions(ProtectionDomain domain) {}

可以返回不可变列表。就我而言，这导致了同样的异常。
