Subcomponent:
Looking at our oop iterator code (at the core of our heap traversal for all GCs) [1]:
"int oopDesc::oop_iterate_size(OopClosureType* cl, MemRegion mr)"
It looks like hotspot has never allocated anything larger than 16 GB, i.e. MAX_VALUE(int32_t) * HeapWordSize (8 bytes).
Look into removing this limitation for large flat arrays
