Since JEP 486 : Permanently Disable the Security Manager
[https://bugs.openjdk.org/browse/JDK-8338625] is now integrated, calls to java.security.AccessController.doPrivileged, and SecurityManager.checkPermission (etc) are obsolete and can be removed.

This bug enumerates files in the jdk.accessibility module that can have these uses removed.
Any SM related imports that are no longer needed they should be removed.

The fix for this should focus on removing these, and exclude any refactoring, reformatting, or other clean up that is not required for this fix.
