JEP 316 - Heap Allocation on Alternative Memory Devices

With this enhancement in Java 10, now user can specify an alternative memory device, like NV-DIMM to HotSpot VM to allocation the java heap space. User need to pass a path to the file system using a new option -XX:AllocateHeapAt.

-XX:AllocateHeapAt=~/etc/heap

This option takes file path and do a memory mapping to achieve the desired result. Other heap flags like -Xmx, -Xms continue to work.
