> There's a discrepancy between removing a bean from the cache 
> after a timeout when bean is in cache compared to when bean is 
> passivated:
> Example, when bean is in cache and has to be removed, this is called:
> if (now - centry.lastUsed >= removalTimeout * 1000)
> {
>   synchronized (centry)
>   {                                                                    
>     it.remove();
>   }
> }
> Now, when bean is passivated, this is called:
> if (now - centry.lastUsed >= removalTimeout * 1000)
> {
>   get(centry.getId(), false);
>   remove(centry.getId());
> }   
> And remove() method calls:
>       if(log.isTraceEnabled())
>       {
>          log.trace("Removing context " + key);
>       }
>       StatefulBeanContext ctx = null;
>       synchronized (cacheMap)
>       {
>          ctx = (StatefulBeanContext) cacheMap.get(key);
>       }
>       if(ctx == null)
>          throw new NoSuchEJBException("Could not find Stateful bean: " + key);
>       if (!ctx.isRemoved())
>          container.destroy(ctx);
>       
>       ++removeCount;
>       
>       if (ctx.getCanRemoveFromCache())
>       {
>          synchronized (cacheMap)
>          {
>             cacheMap.remove(key);
>          }
>       }
> What this means is that when a bean in cache is removed:
> 1.- removeCount is not updated
> 2.- container.destroy(ctx); is not executed and hence the @PreDestroy
> method is not executed either. With regards to this, spec says:
> Spec 4.4 "Note that a container can also invoke the PreDestroy method 
> on the instance without a client call to remove the session object after 
> the lifetime of the EJB object has expired."
