+/** A repository of "shared secrets", which are a mechanism for
+ calling implementation-private methods in another package without
+ using reflection. A package-private class implements a public
+ interface and provides the ability to call package-private methods
+ within that package; the object implementing that interface is
+ provided through a third package to which access is restricted.
+ This framework avoids the primary disadvantage of using reflection
+ for this purpose, namely the loss of compile-time checking. */
