[8] Code Review Request for 8004044: Lazily instantiate SunJCE.RANDOM

[Sean Mullan]

Please review the following webrev which lazily initializes the 
SecureRandom object used by the SunJCE provider.

In JDK 9, we want to load JCE providers with java.util.ServiceLoader as 
part of the transition to modules. This can cause potential recursive 
loading issues if the Sun provider for SecureRandom has not been loaded 
yet (since providers are loaded in no specific order using 
ServiceLoader). The fix is to lazily instantiate SunJCE.RANDOM. This is 
a proactive fix that will smooth the transition to modules.

There is no regression test as this is a small refactoring that is 
covered by existing tests. The bug has been tagged with the 
noreg-cleanup label.

The bug is not up on bugs.sun.com yet.
