Error when starting a service based on second level of inheritance from base_service. #89

Closed hecktor-droxit closed 5 years ago

hecktor-droxit commented 5 years ago

It seems to be impossible to start a service which is a "subsubclass" of base_service (second level of inheritance. In this case, "str_service.StrService" is the direct subclass of "base_service" whereas "lowercaser.Lowercaser" is derived from "StrService".

The above exception was the direct cause of the following exception:

Indicating full path to implementation file in user's home directory solves the issue. Therefore, the "full path" variant to indicate service implementation should be preferred. The "classpath" variant is unintuitive and prone to errors.
