title: Ehcache and Apache JCS - how this work?
body: <p>I need Lru cache to store several (~100) huge object (~10MB for example).
  I read about Ehcache and JSC and have one question. I have the case:
  I store 10 object in ehcache. Then i get one from them and assign to reference. Whether data in my reference object and cache are duplicated or indicate to the same object in JVM memory? </p>
