Mark Thomas commented on POOL-122:
----------------------------------
This has been fixed by logging the throwable (to stderr) and trying to carry
on. Note that exceptions are still silently swallowed.
> java.util.Timer in EvictionTimer does not recover from OutOfMemoryError in
> Evictor

> Key: POOL-122
> URL: https://issues.apache.org/jira/browse/POOL-122
> Project: Commons Pool
> Issue Type: Bug
> Affects Versions: 1.3, 1.4
> Environment: any
> Reporter: Marcus Schulte
> Fix For: 1.5
>
> Attachments: fixes_POOL-122.patch
>
>
> GenericKeyedObjectPool.Evictor.run() catches and ignores Exceptions, but not
> Errors, like OOME. Consequently, when, due to load-peeks an OOME is thrown in
> the evictor's timer-thread it dies miserably and no eviction will happen
> again in any of the pools loaded within the same class-loader (because the
> eviction timer is a static member). Also, the creation of evicting pools will
> fail with IllegalStateException.
> Possible fixes:
> 1. catch Throwable in GenericKeyedObjectPool.Evictor.run()
> 2. check and eventually re-instantiate the Eviction-Timer.
