Hi Sijo, 

If you add a patch against  the current trunk to the issue I guess the devs 
will be happy to apply it ;-)

> LRU Cache is not handling duplicates while parallel inserts

>                 URL: https://issues.apache.org/jira/browse/IBATIS-552
>             Project: iBatis for Java
>          Issue Type: Bug
>          Components: SQL Maps
>    Affects Versions: 2.3.2, 2.3.3
>         Environment: Windows XP
>            Reporter: Sijo Mathew
>
> While using LRU cache with multiple threads and if the threads are querying 
> the same data it is possible to insert duplicate values to the LRU Cache. 
> Even though the internal HashMap handles duplicate keys, the LinkedList used 
> to track least recently used keys is not handling duplicates. So, the 
> external list will grow with each duplicate key but you will have only unique 
> keys inside the map. If there are too many multiple inserts with duplicates, 
> the Cache limit will never be reached as iBatis compares the limit with the 
> size of the LinkedList. 
> It can also be fixed easily by adding a line to check for duplicates before 
> adding the key to the LinkedList.
> Given below is the log for an example run (I have added some extra log 
> messages inside the LRUController) with LRU size as 10 and 4 threads reading 
> values simultaneously. The internal Map Size and the size of the LinkeList 
> are printed in the logs.
