title: Open source alternative for ehcache with synchronousWrites for data consistency
body: <p>I'm using Ehcache 2.4 (release in April. 2011) for caching around 1 million items at ~3000put/sec. </p>
  
  <p>Ehcache is build to detect data inconsistency on start and clean it up if it's the case. My main issue is I'm getting in this situation too often to be able using it properly. </p>
  
  <p>Most of the time, my JVM shuts down too quickly (for many project related reasons) to let the CacheManager shut down properly. I have already tried to enable the ehCache hook.</p>
  
  <p>Two question :</p>
  
  <ul>
  <li><p>On ehCache > 2.5, i saw a new option : "synchronousWrites", but it's an enterprise option ... So is there any others option I can try to have a stronger cache consistency with the non-enterprise version?</p></li>
  <li><p>Is there any others open-source Java cache, better than eHcache for cache consistency ?</p></li>
  </ul>
