Proposed change aimed to keep coherence between variable declaration and static initialization code, which inserts 9 values, not 8, into these two variables.

Although changing the expectedMaxSize supplied to the IdentityHashMap(int) constructor from 8 to 9 likely will not change the actual initial (and final) capacity of the map, I don't see any harm in aligning the expected maximum size with the known maximum size for an IdentityHashMap.
