      Description

      To support new kind of memory devices which are exposed through a file system, Java should provide an option to use a file system for object heap allocation.
      An example is the DAX mode added to Ext4 file system in Linux Kernel 4.0 onwards. DAX was developed in order to support new kind of memories like NV-DIMMs including Intel 3D XPoint.

      This option would facilitate allocating Java heap on non-DRAM memory which will be part of a heterogeneous memory system
