[lworld] Flat array allocations are limited to 16 GB

XMLWordPrintable

    • gc

      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
