    Description

      The ReservedSpace::first_part(..., split=true) API calls os::split_reserved_memory(), which cannot be implemented correctly on Windows (JDK-8253649) and if the underlying memory was not allocate by mmap (JDK-8257040).

      It's used only by CDS (to be removed in JDK-8255917) and heterogenous heap (to be removed in JDK-8256181).

      Afterwards, we should remove these two APIs to avoid future misuse.
