The fix to IdentityHashMap looks good. It is surprising that it wasn't 
caught by tests in the jdk repository so a reminder that we always need 
to check that we have good test coverage when doing performance fixes.

The webrev suggests you've replaced Map/Collisions.java and assume that 
is not the intention. Otherwise the new test looks okay, an alternative 
would have been to expand MOAT.
