/**
 * This jersey2 feature will ensure that there is always a hibernate session
 * available in the current request context. It is important to keep mind of
 * scope here: Sessions are scoped by request, while the SessionFactory is
 * scoped as a singleton. In other words, if you need a session in a context
 * lifecycle listener, then you should construct it by injecting the
 * SessionFactory first.
