Description

Previously our approach was to use the LoadedLifecycleListener and inject services at that point. However, it turns out that this callback is only called when all of the fields/properties in the default fetch group have been loaded; in other words it is indeterminate as to when it is called. The consequence of this is that any attempt to invoke an action on the domain object may result in a NPE if it tries to use a not-yet-injeted service or the container.

This ticket is to hook into JDO/DataNucleus' SPI in order to do the necessary injection.
