I disagree, the application (or application developer) should do that
(preparing statements every time it needs it). It is the driver and/or
connection pool that should keep a pool of prepared statements (see
section 11.6 of JDBC 4.1) for reuse.

The application (and its developer) should not be bothered with keeping
track of prepared statements.

Interesting read. However keeping track of connections and statements as
part of your application makes it more complex and puts responsibilities
in your application that don't belong there. It also duplicates what
connection pools (including statement pools) could be doing for you.
