      Description

        Shenandoah uses MaxHeapSize to calculate region size, then aligns up heap size to region size alignment, but when it calculates region count, it does not take alignment into account, that may result 1 region short than actual count.

        MaxHeapSize eventually aligns to to HeapAlignment (which is region size in Shenandoah case), but it is too late.
