Hi. I'm designing Tile Cache for mapping service. I'm using Jboss Cache. I want to cache Tiles. Tiles are instances of class Image from SWT package. Those Images have dispose() method that should be called when You don't need the Image anymore.

I would like to invoke this method when node in cache that contains Image tile is evicted. I need this only for local cache on client application without replication and clusterring. I tried to make TileEvictionActionPolicy with such method:

@Override
 public boolean evict(Fqn fqn) {
 try
 {
 System.out.println("Start Eviction of: " + fqn);
 if (log.isTraceEnabled()) log.trace("Evicting Fqn " + fqn);
 Node<String, Object> node = (Node<String, Object>) cache.getNode(fqn);
 Image img = node.get("tile");
 if (img!= null && !img.isDisposed())) {
 img.dispose();
 }
 cache.evict(fqn);
 return true;
 }
 catch (Exception e)
 {
 if (log.isDebugEnabled()) log.debug("Unable to evict " + fqn, e);
 return false;
 }

 }

But I notice that when I call in this method cache.getNode(fqn) then I have another node evicted too and I don't know what to do.

Is there any place to controll node removal from cache. I would like to call dispose() on Image that is evicted because of node limit in LRU strategy.
