The source code for the JDK is available for evaluation or educational
or research purposes. You should read the source evaluation
license and decide if that works for you -

http://java.sun.com/products/jdk/1.1/source.html

We don't have an analysis of our PRNG at the level you are asking
about. I'm not aware of a hardware PRNG from Sun.
