java.lang.IllegalStateException: Reading is not available in state Reading

[ScottPierce]

I'm seeing this bug in ktor client 1.1.3 on Android with OkHttp as the engine. It appears to have been a bug since at least ktor 1.0.1. You can see people posting this bug here: https://github.com/ktorio/ktor/issues/813

@e5l readRemaining() does never use lookahead nor readSession so it is unlikely kxio's bug. Most likely it is some kind undesired concurrency.

We're rebooting the kotlinx-io development (see https://github.com/Kotlin/kotlinx-io/issues/131), all issues related to the previous versions will be closed. Consider reopening it if the issue remains (or the feature is still missing) in a new version.
