According to the spec diff new overriding methods are added to TLR:

  http://cr.openjdk.java.net/~psandoz/tl/JDK-8023155-Random-TLR-SR-sync/specdiff/java/util/concurrent/ThreadLocalRandom.html

  http://cr.openjdk.java.net/~psandoz/tl/JDK-8023155-Random-TLR-SR-sync/specdiff/java/util/Random.html

Is that sufficient motivation to add @since to such methods on TLR?

OK. I like the idea of an interface but i am concerned we don't have enough time to flesh out the contract. Personally i would prefer to manage this webrev minus an interface, otherwise i fear we will never get the patch in!

Paul.
