- * Access control context and permission checker.
- * Can check permissions in the access control context of the current thread
- * through the <code>checkPermission()</code> method.
- * Manipulates the access control context for code that needs to be executed
- * the protection domain of the calling class (by explicitly ignoring the
- * context of the calling code) in the <code>doPrivileged()</code> methods.
- * And provides a <code>getContext()</code> method which gives the access
- * control context of the current thread that can be used for checking
- * permissions at a later time and/or in another thread.
- * <p>
- * XXX - Mostly a stub implementation at the moment. Needs native support
- * from the VM to function correctly. XXX - Do not forget to think about
- * how to handle <code>java.lang.reflect.Method.invoke()</code> on the
- * <code>doPrivileged()</code> methods.
