Review Comment:
yeah, I had similar iffy feelings on whether a warning is appropriate. But
info level definitely seems too light to express a genuine problem. It is a
connection error. But the default behavior is to reconnect forever.
Technically, I think this is roughly equivalent to a "Connection Reset" error,
which usually is (forcibly) viewable by the end user. But the code for infinite
retries basically makes the choice for the user. The best code design would
probably include some user-level choice about whether to silently retry forever
or be notified. I tried to stay away from edited the code logic… otherwise I'd
want to rewrite almost all of it. :-)
Maybe this would be best: make it log at the info level and add
documentation at least stating that it will retry forever, and connection error
details will only be available at the info level. Although there is an
exception at this point in the code and the `info` level doesn't accept logging
a `cause: Throwable`. We could `toString` it any of several different ways.
Additional opinions on what log level is appropriate would be appreciated.
