There was a problem hiding this comment. Yeaaaah.... The usage of the different clients is something that really should be refactored and cleaned up. Same with the loggers. We should have established rules which client(s) and which logger(s) is used where, (i.e. CLI code, Manager code and shared code), but that's a discussion for a different time :) |
