[jira] [Created] (POOL-264) NullPointerException in GKOP.borrowObject()

Leonid Meyerguz created POOL-264:
------------------------------------

             Summary: 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.
