### What changes were proposed in this pull request? This PR regenerate the benchmark results in `core` and `mllib` module in order to compare JDK8/JDK11 result. ### Why are the changes needed? According to the result, For `PropertiesCloneBenchmark` and `UDTSerializationBenchmark`, JDK11 is slightly faster. In general, there is no regression in JDK11. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? This is a test-only PR. Manually run the benchmark.
