    When a module declares that the provider class is created by a provider factory then this method returns the return type of its public static "provider()" method.

    Throws:
    
    ServiceConfigurationError - If the service provider cannot be instantiated, or in the case of a provider factory, the public static "provider()" method returns null or throws an error or exception. The ServiceConfigurationError will carry an appropriate cause where possible.
