testGIIAndMapUpdates

public void testGIIAndMapUpdates()

Tests the relevant data structures are updated after GII happens. In this test, a HARegion is created in vm0. 10 conflatable objects are put in vm0's region HARegion is then created in vm1. After region creation, the verification whether the relevant data structuers have been updated is done.
