Is it -XX:HeapDir or -XX:AllocateHeapAt ?  JEP says AllocateHeapAt, impl
does not.

+                                                                            \
+  product(ccstr, HeapDir, NULL,                                             \
+          "Path to the directoy where a temporary file will be created      \
+           to use as the backing store for Java Heap.")
