Selective setAccessible permissions using Byte Buddy and the Java SecurityManager

The Java SecurityManager provides a lot of good permissions for restricted what untrusted code can access. The downside of the standard permissions is that many of them are too broad, making it hard to enable permissions around commonly used functionality without defeating the purpose of the restricted security. The permissions around reflections are one of these cases, where the permissions around the setAccessible reflections method is either all on or all off.
