java.lang.NoClassDefFoundError: java.util.Objects when using OkHttp with Ktor 1.2.0+

[nolanamy]

Ktor Version and Engine Used
io.ktor:ktor-client-okhttp:1.2.4

Describe the bug
java.lang.NoClassDefFoundError: java.util.Objects in OkHttp

See OkHttp 3.13 Requires Android 5+ linked from issue square/okhttp#4716

Do I have to configure my own OkHttp instance (as requested here #903)? Can I do that given that Ktor includes a newer version of OkHttp?

To Reproduce
Call HttpClient() on Android 4.x

Well, starting from that version okhttp requires Android 5 so there is nothing to do with ktor. Currently, we depend on 3.14.2.

It's OkHttp version issue. I'm not sure that we're going to support old versions of OkHttp, consider using Android engine instead
