Random number generation is usually just a tiny fraction of a larger algorithm, and the SecureRandom instance is rarely contended outside of microbenchmark setting. And if it's not contended, users will only pay the cost of using a ThreadLocal for no real benefit. ------------- PR: https://git.openjdk.org/jdk/pull/11069
