LDAP Connection pooling not working

Hi, when running openfire with LDAP for the groups and users I noticed it would take quite a bit of time to load the users and groups. In searching for the bottleneck I found that connection pooling would appear to be broken in 3.8.1

I have ldap.connectionPoolEnabled = true

For example here are the connections when navigating to the users tab in the management console right after starting the server (not much cached). I would expect to see a bunch of established connections and maybe a few closed ones, but instead there’s a massive amount of closed connections and the connections don’t last for the 10 second default when doing pooling in Java.

Am I missing something or is this indeed a bug?
