the problem is more that the binding tries to update all group members, for example the currently track information. As you have not these things, there is a log message.
But in this case (group slaves), I agree that we should just ignore them if the thing does not exist.
I will think about a fix.

If I understand this change correctly, you changed the log level if an illegal state exception has been catched. Is the reason "no such thing available" the only cause of that exception?

Using info logging at these places is not in line with our logging guidelines. So I would say that it should either stay a warning (in case this is a software or general setup bug and we should usually never get here) or it should be logged as debug only.

Yes, "No such thing available" is the only cause of the exception.

And if INFO level should never be used except for important things, yes we should replace with DEBUG level.
