Weird stuff in test framework

[Dawid Weiss]

Hi. As part of working on LUCENE-3492 I've been copy-pasting chunks of
existing code. If you can peek at the diff in the attachment some of
the things got me thinking...= One seems to be a bug/ overlook (unused
parameter), but the other is my personal candidate for the most weird
snippet of the month :)

         int newInt = new Random().nextInt();
         counter = ((newInt / 65535) & 0xFFFF) + 0x2710;

Was this intentional? Who wrote that and, most of all, what is it
intended to do? :)
