Examples of sun.security.action.GetPropertyAction

sun.security.action.GetPropertyAction
A convenience class for retrieving the string value of a system property as a privileged action.
An instance of this class can be used as the argument of AccessController.doPrivileged.
The following code retrieves the value of the system property named "prop" as a privileged action:
```
 String s = java.security.AccessController.doPrivileged (new GetPropertyAction("prop")); 
```
