Indeed there was 2 pools as per answered by Jean.

But in my case here, my project is loaded into Jetty server which was initialized by Spring.

Also inside Jetty server - it was creating container for Spring beans that were getting initialized from service-context.xml file.

So It was getting called twice that leads to the creation of two pools

Thanks you all those who commented and tried solve my issue. Means a lot :)

From the log, you have several several pools running: pool-1 and pool-3.

You might want to make sure you only initialize one pool.
