      Description

      The fix for JDK-8225670 caused a performance regression with several benchmarks and therefore needs to be backed out and re-worked.

      For example:

      Benchmark Mode Cnt Score Error Units
      MonteCarlo.monte_carlo thrpt 15 98.821 ± 13.039 ops/min

      vs.

      Benchmark Mode Cnt Score Error Units
      MonteCarlo.monte_carlo thrpt 15 301.324 ± 40.006 ops/min
