Update the SSLHandshake benchmark to enable running in multiple threads. This PR changes the scope of the state from per-benchmark to per-thread. The server SSLContext is still shared across all threads to simulate the scenario where multiple clients try to connect to the same server at the same time.
Before the change, running this benchmark with `make test TEST=micro:SSLHandshake MICRO=OPTIONS="-t 3"` failed with an exception. After this change the benchmark completes successfully. ------------- Commit messages: - Remove outdated comments - Initialize server SSLContext once - Run benchmark in multiple threads Changes: https://git.openjdk.org/jdk/pull/24195/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24195&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8350705 Stats: 33 lines in 1 file changed: 20 ins; 6 del; 7 mod Patch: https://git.openjdk.org/jdk/pull/24195.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24195/head:pull/24195 PR: https://git.openjdk.org/jdk/pull/24195
