----------------------------
> Thread stuck in GenericObjectPool borrowObject()
> ------------------------------------------------
>
> Key: POOL-147
> URL: https://issues.apache.org/jira/browse/POOL-147
> Project: Commons Pool
> Issue Type: Bug
> Affects Versions: 1.5.1
> Reporter: Giambattista Bloisi
> Priority: Minor
> Fix For: 1.5.2
>
> Attachments: 01-borrowObject.patch
>
>
> In my application I found a thread stuck at
> GenericObjectPool.borrowObject(GenericObjectPool.java:1099) even though
> resources were availbale (in my case connections for DBCP).
> After an analysis of the code I think I spotted what could have caused this
> behavior. GenericObjectPool.java:1099 line corresponds to an indefinite wait
> to a "latch" object. This wait should be awaken when new resources are made
> available to the pool. The problem is likely that borrowObject enters in wait
> without performing "latch.getPair()" check in a critical section.
