/**
 * AriesApplicationManager requires that there be at least one

 * implementation: it simply returns the bundles that it was provided with -
 * enough to permit the testing of Aries applications that have no external
 * dependencies. It is not intended to be used in a production environment, as
 * the implementation of the AriesApplicationResolver just returns the bundles
 * included in the application irrespective of what is specified in
 * application.mf.
