public class OpenNMSConfiguration
extends Configuration
Outside of Karaf (ie, in the "system" bundle) we need to use the springframework-security version of
 the OpenNMSLoginModule run.  We can't share login modules because of classloading boundaries, and
 the peculiar way that Karaf wraps login modules in a proxy class.
 Additionally, there are some cases where we wish to use the system's JAAS configuration.
 To achieve this, we gather all of the configuration implementations until the
 Karaf implementation is loaded (this implementation is currently loaded last in the startup
 process). When a request is made, we then delegate to all of the known implementations.
