Any Java caches that can limit memory usage of in-memory cache, not just instance count?

Question

I am looking for a simple in-memory (and in-process) cache for short-term caching of query data (but short-term meaning beyond request/response, i.e. session boundary). EhCache

EhCache V2.5 currently offers a solution which can cap based on the memory size of the cache. For more details checkout EhCache 2.5 Documentation
