Update ThreadLocalRandom benchmark to show issues with contention ( #8292 )
...
Previous benchmark was measuring initialization of thread pools and
their shutdown, not really measuring performance of Random.nextInt()
shared Random instance vs ThreadLocalRandom.current()
Example when run with 8 threads
