It's worth repeating:  Unsafe is only for internal use by the JDK.  The access restrictions on it,
which are often circumvented, are going to be strengthened by the JDK 9 module system,
and the restrictions will become harder to circumvent.

Use it for experiments if that's useful, but don't build it into your product.

For more information, check out Paul Sandoz's talk on unsafe and varhandles at Java One 2014.
