LUCENE-4975: make forbidden-apis shut up: "new Random()" is bad, and LTC.random() says "RandomizedRunner prevents changing the seed of its random generators to assure repeatability of tests. If you need a mutable instance of Random, create a new instance, preferably with the initial seed aquired from this Random instance.", so switched to "new Random(random.nextLong())"
