ManagedChannelImpl was not shutdown properly

[jasperrosiers]

The error I put below, where a ManagedChannel was not shut down properly. I have read this issue, but couldn't find a solution: .

I have basically completely copied the code from Google's docs. I will put the faulty class below the error as well. I have tried finding a "shutdown" method on all of the variables, but there aren't any, so I'm not sure what I should do.
