Motivation: As reported in #4402, the FastThreadLocalBenchmark shows that the JDK ThreadLocal is actually faster than Netty's custom thread local implementation. I was looking forward to doing some deep digging, but got disappointed :(. Modifications: The microbenchmark was not using FastThreadLocalThreads and would thus always hit the slow path. I updated the JMH command line flags, so that FastThreadLocalThreads would be used. Result: FastThreadLocalBenchmark shows FastThreadLocal to be faster than JDK's ThreadLocal implementation, by about 56% in this particular benchmark. Run on OSX El Capitan with OpenJDK 1.8u60.
