6810254: Lazily instantiate the shared secret access objects
Webrev at: http://cr.openjdk.java.net/~mchung/6810254/webrev.00/sun.misc.Java*Access objects are created at initialization time. However, they are not always needed. They can be instantiated lazily when needed. The fix is to add a static setSharedSecret() method to be called by sun.misc.SharedSecrets via reflection when the shared secret access object is requested.
Thanks Mandy
