Jython's random implementation

I've looked in the random package in Jython 2 and Jython 3 for Jython's random implementation. I see that it's using Java's LCG (as confirmed by the docs) but not much else. I tried GrepCode and even downloaded the source to see if Windows search could maybe find it. I was looking for the source for all the other functions in the random library simply because I'd like to see how Jython does it.
