Subject [jira] Updated: (POOL-97) EVICTION_TIMER is never cancelled.
Date Sat, 23 Jun 2007 20:02:26 GMT


Phil Steitz updated POOL-97:

    Attachment: timer.patch

Attaching a patch (timer.patch) that makes the eviction timer a (lazy initialized) instance
variable in GOP, GKOP and cancels it in close.   Questions:

1. Will this resolve the issue fully? 
2. Other than additional overhead in multi-pool settings, are there other negatives to this?
How "bad" is the overhead issue?
3. Does the fix introduce any other problems?

> The static EVICTION_TIMER (java.util.Timer) used in GenericObjectPool is never cancelled
(even after closing the pool). The GenericObjectPool.close() method just cancels the _evictor
(TimerTask). I agree this behaviour is ideal if EVICTION_TIMER is to be used across multiple
> But, In my case, the resources (i.e. jars) are dynamically deployed and undeployed on
remote grid-servers. If EVICTION_TIMER thread doesn't stop, the grid-servers fails to undeploy
(i.e. delete) the jars. The grid-server doesn't restart during resource deployment/undeployment,
so, setting EVICTION_TIMER to daemon doesn't help me.
