Understood, and for tests, @ContextConfiguration takes an initializers
parameter. But, our ReloadableSpringService class uses
SpringSupport#newContext() to create a new application context, so we
will have to apply the custom app ctx initializer manually, IIUC. Most
of those services are in system/conf/services-system.xml, I think.
