RFR(XS): 8075071: [TEST_BUG] TimSortStackSize2.java: OOME: Java heap space: MaxHeap shrinked by MaxRAMFraction

[Lev Priima]

Hi David,

Explicit -Xmx does not allow explicit MaxRAMFraction to shrink 
MaxHeapSize down to -Xms(or even less down to default InitialHeapSize in 
case if -Xms also wasn't set explicitly). In other words explicit -Xmx 
has priority over explicit MaxRAMFraction if both are set and contradict 
with each other.
