Daniel Feist updated COLLECTIONS-520:
-------------------------------------
Description:
Java provides implementations for List's and Set's but Map is missing.
Jersey uses an implementation
([com.sun.jersey.client.impl.CopyOnWriteHashMap|https://java.net/projects/jersey/sources/svn/content/trunk/jersey/jersey-client/src/main/java/com/sun/jersey/client/impl/CopyOnWriteHashMap.java])
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).
See:
[org.mule.util.CopyOnWriteCaseInsensitiveMap|https://github.com/mulesoft/mule/blob/716893e6231be47dccd3cfba9619762e146b4b84/core/src/main/java/org/mule/util/CopyOnWriteCaseInsensitiveMap.java]
