> A user reported these two issues when trying to run a top level pear.  See http://markmail.org/thread/jbacko4l6jyonzse 
> A discussion with Adam L indicates the problem may be being caused by the fact that the PearSpecifier interface extends the ResourceServiceSpecifier, and things would work better if it extended the ResourceCreationSpecifier - in that the cause of the NPE which is a null value for the map representing the configuration parameters, in the method ConfigurationManagerImplBase.validateConfigurationParameterSettings.  This map is setup by Resource_ImplBase if the specifier is a subtype of ResourceCreationSpecfier, but not otherwise.
> Also, the *session* is setup, but again, only if the specifier is a subtype of ResourceCreationSpecifier.  So, the first thing to investigate is to see if we can switch this, and what the impact would be.
