Scala : Unreleased resource database

The method creates a database resource (such as a database connection or row set), does not assign it to any fields, pass it to other methods, or return it, and does not appear to close the object on all paths out of the method. These may result in poor performance, and could cause the application to have problems communicating with the database.

Reliability of software falls. An atacker might initate a resource leak, and be able to lauch a denial of servise attack by depleting the resource.
