6843694: G1: assert(index < _vs.committed_size(),"bad index"), g1BlockOffsetTable.inline.hpp:55
Summary: For heaps larger than 32Gb, the number of heap regions overflows the data type used to hold the region index in the SparsePRT structure. Changed the region indexes, card indexes, and RSet hash table buckets to ints and added some size overflow guarantees.
