    Description

      $ ./jdk-15/fastdebug/bin/java -XX:+UseG1GC -XX:+UseNUMA -XX:+ForceNUMA -version
      # To suppress the following error report, specify this argument
      # after -XX: or in .hotspotrc: SuppressErrorAt=t:/workspace/open/src/hotspot/os/windows/os_windows.cpp:2912
      #
      # A fatal error has been detected by the Java Runtime Environment:
      #
      # Internal Error (t:/workspace/open/src/hotspot/os/windows/os_windows.cpp:2912), pid=9256, tid=18272
      # assert(numa_node_list_holder.get_count() > 0) failed: Multiple NUMA nodes expected

      The specific choice of GC probably doesn't matter for this.
