   Fixes 
[COLLECTIONS-887](https://issues.apache.org/jira/browse/COLLECTIONS-887)
   
   Added `Objects.requireNonNull(key, "key")` to `remove(key)`, `remove(key, 
value)`, `replace(key, value)`, and `replace(key, oldValue, newValue)` in 
`ConcurrentReferenceHashMap` to ensure null key contract is enforced explicitly 
and consistently regardless of map configuration.
