 /** 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. */
