I don't see a pointer to the webrev/patch -- did you forget to include it?

Thanks to Peter for digging into the secure seed generator classes and coming up with a patch. Openjdk security folks, please review. I confess to getting lost whenever I try to orient myself in the twisty maze of seed generator implementation files.

Anyways, it seems important to have prngs like ThreadLocalRandom be able to get a few bits of seed entropy without loading hundreds of classes and without occupying any file descriptors permanently. Perhaps at Google we will go back to writing some simple non-portable startup code to read /dev/urandom until openjdk security team comes up with a more principled solution (but one that doesn't drag in too much machinery).
