[jira] [Created] (CAMEL-10988) Improve performance of CaseInsensitiveMap

Marcin Lachowicz created CAMEL-10988:
----------------------------------------

             Summary: Improve performance of CaseInsensitiveMap
                 Key: CAMEL-10988
                 URL: https://issues.apache.org/jira/browse/CAMEL-10988
             Project: Camel
          Issue Type: Improvement
          Components: camel-core
    Affects Versions: 2.18.2
            Reporter: Marcin Lachowicz


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.
