> Guava has become a common library used in many projects.
> Provided default implementation (MemoryConstrainedCacheManager) seems to retain data in cache for too long for common cases.
> Others implementation (ehcache, terracotta) require the developper to add some dependencies.
> Guava provides a caching API [1]. It's convenient since it's in-memory and thread-safe, Guava has a mature quality code base and it support few tweaking options:
>     concurrencyLevel
>     initialCapacity
>     maximumSize
>     maximumWeight
>     expireAfterAccess
>     expireAfterWrite
>     refreshAfterWrite
>     weakKeys
>     softValues
>     weakValues
>     recordStats
> I've already programmed the whole thing (patch provided) and I was wondering if the Shiro team would be interested to integrate this as a new module. It's tiny (no dependency except guava and shiro-cache).
> We could just put this CacheManager implementation in shiro-core or in shiro-cache module or in it's own module (but i think a module for a single class is overkill). 
> It's not perfect but i did some Javadoc.
