I looked in the AbandonedObjectPool code and found the following.
if (config != null
&& config.getRemoveAbandoned()
&& (getNumIdle() < 2)
&& (getNumActive() > getMaxActive() - 3) ) {
removeAbandoned();So, I never came close to the abandoned connections being removed because my max active was set to 20 or something, and I had only a couple of dangling connections. I thought this would be done in a background thread, but I guess not.

I have the following code, and it doesn't clean up abandoned connections. Anybody have an idea of what I am doing wrong?
