[logback-user] SyslogAppender: "Will try to reconnect later"

I'm perusing SyslogAppenderBase and noticed something that seems wrong. If createOutputStream throws SocketException, the warning says "Failed to bind to a random datagram socket. Will try to reconnect later." But it doesn't increment errorCount, super.start gets called, and as far as I can tell the `append` method will then throw NullPointerException attempting to dereference `sos`. I see no code that tries to reconnect as the warning message says it should. Does this look like a mistake, or am I misreading something?
