Hi,

Sure. Reflection uses access control as intended, so that you can use
reflection for package and protected members within the current package
as well.

If the field is inaccessible normally, see the setAccessible method in
AccessibleObject (which is a base class for Field, Method, and
Constructor). It lets you bypass access control. This is subject to a
check by the SecurityManager to prevent untrusted code from using this
feature to circumvent security checking.

Serialisation manages to reflect even private ones.

You might wonder how serialisation manages to get at the non-transient
private members via reflection. It uses
AccessController.doPrivileged() to override the general security
privileges
