Discrepancies between removing a bean in cache vs bean passivated

Key: EJBTHREE-1500

Reporter: Galder Zamarreno

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 @Remove
method is not executed either.

-----------------------------------------
Contradicts 4.4.3 bullet 3:
The following scenarios result in the PreDestroy lifecycle callback interceptor method(s)
not being called for an instance:
...
• A timeout of client inactivity while the instance is in the passive state. The timeout
is specified by the Deployer in an EJB container implementation-specific way.

Galder Zamarreno commented on EJBTHREE-1500:
--------------------------------------------
Hmmm, let's clarify all this:
1.- When timed out bean from passivated state is removed, we currently do:
- a) invoke pre destroy method
- b) update removeCount
- c) remove context from cache map
2.- When timed out bean from ready state is removed, we currently do:
- a) remove context from cache map.
Now, taking in account your statement, we should be fixing this:
- 1a) needs to be removed as per 4.4.3.3
- We need to update removeCount for 2.
- Optionally: call pre destroy when bean removed in 2 as per 4.4
