Ronny noticed the other day that the trick documented in the Performance Tuning wiki article to count alive poller threads no longer works in 1.12. I dug in a bit and found that the RunnableConsumerThreadPool is gone now, seemingly replaced with WaterfallExecutor. I haven't studied the new class structure but presumably it still uses a thread pool in a roughly comparable way. Can we put in a similar log message, or document in the wiki whatever existing message people should be looking for instead?
