sun.security.action has a few convenient class that JDK classes use and the callsite looks like this:

   AccessController.doPrivileged(new GetPropertyAction(propertyName));

This leads to many jdk modules depending on these module-private API in the base module.

With lambda, these usages can be replaced with:

   AccessController.doPrivileged(
       (PrivilegedAction<String>) () -> System.getProperty(propertyName));

The use of these convenient classes is not absolutely necessary and in fact the action is made more explicit in the callsite which has the benefit. I propose to eliminate the cross-module dependency to sun.security.action to reduce the number of the base module-private APIs being used by other jdk modules.
