Heap capacity is in size_t. Which means expressions like this are subject to overflow:
size_t min_threshold = ShenandoahMinFreeThreshold * heap->max_capacity() / 100;
Consider the x86_32 case with max_capacity = 1G. ShenandoahMinFreeThreshold >= 5 overflows it.
size_t min_threshold = ShenandoahMinFreeThreshold * heap->max_capacity() / 100;
Consider the x86_32 case with max_capacity = 1G. ShenandoahMinFreeThreshold >= 5 overflows it.
