--------------------------------------
Hi Phil,
Thanks for the quick response! The workaround is exactly what I ended up
doing. Haven't had issues with it so far, but didn't yet test it at the scale
where we found the original NPE.
Best Regards,
Leonid.
> NullPointerException in GKOP.borrowObject()
> -------------------------------------------
>
> Key: POOL-264
> URL: https://issues.apache.org/jira/browse/POOL-264
> Project: Commons Pool
> Issue Type: Bug
> Affects Versions: 1.5.6
> Reporter: Leonid Meyerguz
>
> While I cannot pin down a consistent repro, I occasionally observe a
> NullPointerException at
> org.apache.commons.pool.impl.GenericKeyedObjectPool.borrowObject(GenericKeyedObjectPool.java:1126)
> The pool is configured as follows:
> maxActive = -1
> maxIdle = 32
> maxTotal = 32
> whenExhaustedAction = WHEN_EXHAUSTED_GROW
> timeBetweenEvictionRunsMillis = 20000
> minEvictableIdleTimeMillis = 60000
> numTestsPerEvictionRun = -1
> The NullPointerException is thrown in the WHEN_EXHAUSTED_GROW branch of the
> code. Specifically it appears that latch.getPool() returns null.
> Any suggestions for a work-around would be appreciated.
