So does
com.espeed.BR.PaymentProcessing.PaymentIniterface.initializeGUI() close
the connection it obtains from the pool?
If it doesn't then that is the cause of your leak. Ideally the code
should get and close connections as needed, and not cache them. If the
code caches a connection then you'd have to size the pool to be big
enough to support the number of concurrent clients so each could have
its own connection - which defeats the object of using a resource pool
which is meant to allow greater reuse of a limited number of resources
between a larger number of clients.
