> CaseInsensitiveMap prevent duplicate key conversion on put

> Key: COLLECTIONS-803
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-803
> Project: Commons Collections
> Issue Type: Improvement
> Components: Map
> Affects Versions: 4.4
> Reporter: Simulant
> Priority: Minor
> Labels: performance
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> When adding a new item into a {{CaseInsensitiveMap}} the {{convertKey(key)}}
> method is called twice, once in the {{put(key, value)}} method and second in
> the {{createEntry(next, hashCode, key, value)}} method. The result could be
> re-used resulting in a better performance.
> Depending on the {{toString()}} implementation of the key and the resulting
> length of the key before the lower case conversion the operation can get
> expensive and should not be called twice, as the {{CaseInsensitiveMap}}
> overwrites the {{convertKey(key)}} method and makes it more expensive and
> depending on the input unlike in the implementation of the
> {{AbstractHashedMap}}.
