It's more idiomatic to call client.use { ... } instead of client.also { ... }. That will call close() automatically.

It's not the point, why client closes automatically in 1.1.1, and required to be closed in 1.2.1. Looks like close method not calling on Engine in both version, code which create AsyncHttpClient is the same. I have no idea what to check also

@e5l how it possible, that JVM terminates without explicit client.close() in 1.1.1?

[e5l]

Client holds runBlocking if some connection is still active. Probably the validate method doesn’t close the response.

[irus]

fun main() {
    val client = AppStoreClient("...", "...")

    runBlocking {
        println(client.validate("..."))
    }

    println("Done")
}

In this case Done will be printed, but JVM:
1. ktor-client:1.1.1 - stopped
2. ktor-client 1.2.1 - keep running
