Jeremy Hughes updated ARIES-138:
--------------------------------

    Affects Version/s:     (was: Incubation)

removed 'affects version' incubation as that is a redundant release

> As a blueprint managed application developer, I'd like some helpful feedback when things aren't working quite as I'd expect. For example, service and service registration listener callback methods "must have a signature matching with the following format":
> 	public void anyMethodName (ServiceType serviceInstance, Map serviceProperties)
> 	
> A programmer might well attempt to register a callback method with signature (ServiceType, HashMap) or (ServiceType, Properties) which will not be called: ServiceRegistrationListener.getSignatureType() is strict on demanding 'Map' as the second parameter type. This is correct, but for a certain level of debug, we could certainly output a message indicating that method signature matching had failed, or that various candidate methods had been rejected. 
> The general requirement here is for programmers to be able to debug their blueprint applications without recourse to the source code :-)
