Because you release JMS resources in @PreRemove method, you have no
control when they are released. @PreRemove methods are invoked when
beans are to be destroyed, maybe long after it has been returned to the
pool. In you app, every bean instance, even when they are in pool,
holds an open connection. Try releasing resources from within your
busines methods.
