I am sorry I did not see the thread dump. I did some testing and I think I now know what is going on. If you add acfg.setLogWriter(new PrintWriter(System.out, true)); you will see the stack trace. This is a bug in Commons Pool. The default logwriter is not set up to autoflush and the DefaultPooledObject (what DBCP uses) does not flush the PrintWriter. Thanks for reporting it and sorry to be slow to dig into it. I will open the pool bug.
