Are you really shure about getConnectionCount() ?
When i start my application with minsize = 5 than getConnectionCount()
returns 5,
with minsize = 4 getConnectionCount() returns 4 at the beginning,
when not using my application for some time getConnectionCount() decreases,
so i thought getConnectionCount() returns the current used connections.
(unfortunatly there is no api-doc for getConnectionCount())
