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
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.
