> 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.
