I never used Jboss, but in Tomcat it works this way and I suppose jboss
has the same behavior.
When you close a connection in your program, you tell your application
server that you don't need it anymore, but it it up to the application
server to close it or not, you only release it from the context use.
In your current setup, your min-pool-size is set to 5, which probably
means that jboss will try to always keep 5 open connections, even if they
are not currently in use. The max size only tells jboss the maximum size
to open at a time.
So if you open 10 connections and close them all, my guess is that 5 will
get closed by jboss but 5 will remain active.
Hope I'm not wrong! :)
