23: * <p>
24: * Some thought has been given to using bytecode generation to create properties for messages,
25: * extension point id, and so forth. This is being avoided because it undermines the ability to test
26: * service implemenations as POJOs, outside the framework of HiveMind.
27: * <p>
28: * Instead the service is configured by means of the implementation's constructor and setter
29: * methods.
