Description
Java provides implementations for List's and Set's but Map is missing.
Jersey uses an implementation (com.sun.jersey.client.impl.CopyOnWriteHashMap) but it doesn't fully implement Map because entrySet/keySet/values are not mutable.
I implemented a CaseInsensitiveCopyOnWriteMap in Mule and while it serves our purposes it's not 100% complete and isn't thread-safe, and it would be good to see an implementation in commons. (BTW: I plan to extend from AsbtractHashedMap once we moved to 4.0/4.1).
