Description

The CaseInsensitiveMap can be optimized as currently we keep 2 maps with the original keys + lower case keys.

But all that can be done from the JDK using a TreeMap with a case insenstice comparator from the JDK itself. This reduces memory (only 1 map) and also better performance as its one map, with the trade-off that walking the map using entrySet no longer supports mutations.
