    36     calling implementation-private methods in another package without

    37     using reflection. A package-private class implements a public

    38     interface and provides the ability to call package-private methods

    39     within that package; the object implementing that interface is

    40     provided through a third package to which access is restricted.

    41     This framework avoids the primary disadvantage of using reflection

    42     for this purpose, namely the loss of compile-time checking. */
