- Instead of Thread.threadLocalRandomSeed field it has a Thread.threadLocalRandom reference field, pointing to an instance of TLR. - The ThreadLocalRandom is not a singleton, but an instance per thread (like JDK7's).
Yes, this is the "Plan B" I mentioned in mail last week. I had explored this. Both on performance and resource grounds, it is a little worse. Not hugely worse, but if we are going to improve TLR, then might as well take the best option. (Another reason to prefer current solution also serves as a reply to Tom: Yes we don't like using Unsafe just to bypass package-protection access control. But at least it is just accessing simple scalars, not references.) -Doug
