RFR: JDK-8056237 [TESTBUG] gc/g1/TestHumongousShrinkHeap.java fails due to OOM

[Dmitry Fazunenko]

Hi Andrey,

Looks good, some minor comments related to better var names

1) PAGE_SIZE --> REGION_SIZE  (if you mean G1 heap reg size)
2) PAGES_NUM --> GROUP_NUM (you divide allocated objects in groups)
3)
USED_MEMORY = Runtime.getRuntime().totalMemory()
I guess you meant
FREE_MEMORY = Runtime.getRuntime().freeMemory()

Thanks,
Dima
