------------------------------------
I would like to encourage you to provide a patch. Ideally, including a unit
test that shows the performance and stability under high parallel load.

> Hi, Thomas
> I'm using JCS 1.3 and found the LRUMemoryCache.get() is synchronized.
> Also, the underlying map is HashTable.
> I have some lock contention when using multiple threads to hit cache.
> Do you have any plan to improve it? (maybe in 2.0.0 release?)
> Thanks
> Ma Leon
