I've just started looking at JBossCache and I was writing some tests to see how 
it works. I am trying to put nodes into the cache and then see them expire. I 
have used a region and used n LRU eviction policy. I was thinking that setting 
TimeToLiveSeconds and/or MaxAgeSeconds would cause the node to be completely 
removed from the cache. I know that the RegionManager has to wake up so I 
setWakeUpIntervalSeconds on the EvictionConfiguration to 4 seconds.


  |                             LRUConfiguration lru = new LRUConfiguration();
  |                             lru.setMaxNodes(5000);
  |                             lru.setTimeToLiveSeconds(2);
  |                             lru.setMaxAgeSeconds(2);
  | 

I did a sleep for 10 seconds and the node was still there.

I then tried doing the following which I found in the user manual.


  |     Long future = new Long(System.currentTimeMillis() + 2000);
  |     
cache.getRoot().getChild(nodeFqn).put(ExpirationConfiguration.EXPIRATION_KEY, 
future);
  |                     
  |     assertTrue(cache.getRoot().hasChild(nodeFqn));
  |     Thread.sleep(10000);
  |                     
  |     // after 5 seconds, expiration completes
  |     assertFalse(cache.getRoot().hasChild(nodeFqn));
  | 

The node was still there.

Then I tried this:


  |                     ExpirationConfiguration ec = new 
ExpirationConfiguration();
  |                     ec.setTimeToLiveSeconds(2);
  |                                                     
  | 
cache.getRoot().getChild(nodeFqn).put(ExpirationConfiguration.EXPIRATION_KEY, 
ec);
  |                     
  |                     assertTrue(cache.getRoot().hasChild(nodeFqn));
  |                     Thread.sleep(10000);
  |                     
  |                     // after 5 seconds, expiration completes
  |                     Node n1 = cache.getRoot().getChild(nodeFqn);
  |                     assertFalse(cache.getRoot().hasChild(nodeFqn));
  | 

The node was still there. So if anyone can tell me what I'm missing I would 
appreciate it. I am expecting to see the node gone from the cache by one of 
these methods. Thanks for any help you can provide.
