> There are many cache implementation in Groovy, many of them are duplicated(e.g. cache
algorithm, the code of implementation...). That is to say, Groovy is lack of a common cache.
> The common cache should:
> 1) has two version: thread-safe and not thread-safe for different senario
> 2) achieve basic cache function(manage keys and values, LRU, etc.)
> 3) can specify the map that the cache is based on(Maybe we need WeakHashMap or other
Map instance sometimes)
> Here is the implementation of the common cache:

> https://github.com/apache/groovy/blob/master/src/main/org/codehaus/groovy/runtime/memoize/ConcurrentCommonCache.java
