      This is a followup to JDK13 updates to refresh internal java.util.concurrent lock usages and support. Quoting internal documentation:
           * * ForkJoinTask now uses field "aux" to support blocking joins
           * and/or record exceptions, replacing reliance on builtin
           * monitors and side tables.
           * * Scans probe slots (vs compare indices), along with related
           * changes that reduce performance differences across most
           * garbage collectors, and reduce contention.
           * * Refactoring for better integration of special task types and
           * other capabilities that had been incrementally tacked on. Plus
           * many minor reworkings to improve consistency.
