NoSuchElementException coming from RouteSelector after upgrading 3.12 -> 3.14

After upgrading our android app from okhttp 3.12.2 to 3.14.0, we started seeing this error (stacktrace below) coming through Crashlytics in production at a very high rate. Because we upgraded directly from 3.12 to 3.14, I’m not sure if this error was introduced in 3.13 or 3.14.

With an admittedly small sample size, the crash was affecting over 10% of sessions and over 20% of users, so we were forced to roll back. It appeared across Android versions 7, 8, 9, and Q.

Unfortunately, I wasn’t able to reproduce it locally. However, it seems very similar to this issue from 2 years ago, which appears to have been re-introduced to the library: https://github.com/square/okhttp/issues/3308

I am not sure if this is related but we are compiling our app with R8 version 1.4.72

Our app uses Java 8, min SDK 21, and the latest version of retrofit (2.5.0).

Hopefully this information and the stack trace below is enough to be helpful, apologies for not being able to include a reproducible case outside of production.

Thank you for the amazing library and everything you do for android open source!

3.14.2 is out and has this fix. Go get it!
