title: Is there concurrent & self-expiring & ordered hash map in java
body: <p>I'm using <code>ConcurrentHashMap</code> from google guava (via MapMaker), but that implementation isn't ordered.
  There is <code>ConcurrentSkipListMap</code> in google guava, but that structure can't expire. </p>
  
  <p>Is there any structure that can do both?</p>
