Claus Ibsen commented on CAMEL-10988:
-------------------------------------

There is a SPI now, so a custom camel-xxx component can be created with an implementation of that other library people can use to configure on camel context

> Current CaseInsensitiveMap bases on TreeMap. 
> Basing on JMH, I found out that [the following implementation of CaseInsensitiveMap|https://github.com/jdereg/java-util/blob/master/src/main/java/com/cedarsoftware/util/CaseInsensitiveMap.java] results with even 50% performance boost, depending on use-case. 
> It uses HashMap with case-insensitive wrappers on String keys.
