--------------------------------
Hi,
would patches specific to the functionality be allowed here ?
Also would the JDK minimum version JCS 2.0 would support be 1.6 ?

> Key: JCS-119

> Project: Commons JCS
> Issue Type: Improvement
> Reporter: Romain Manni-Bucau
> Fix For: jcs-2.0

>
> A cache is typically used in a concurrent environment. Since Java 6 using a
> ReentrantLock is faster than synchronized so can be interesting to replace
> synchronized blocks by a lock.
> Places i'm thinking about:
> * CompositeCache
> * AbstractDoubleLinkedListMemoryCache
> * LHMLRUMemoryCache
> * DoubleLinkedList
> * LRUMap
> * SingleLinkedList
> * SortedPreferentialArray
> Some places where replacing a HashMap by a ConcurrentHashMap can allow to get
> rid of synchronized without needing a lock:
> * CacheEventQueue
> * AbstractDiskCache
> * CacheWatchRepairable
> There are other places but this is the main I saw.
