 *  Fix: Don't reuse a connection on redirect if certs match but DNS does not. For better
    locality and performance OkHttp attempts to use the same pooled connection across redirects and
    follow-ups. It independently shares connections when the IP addresses and certificates match,
    even if the host names do not. In 4.4.0 we introduced a regression where we shared a connection

    client.send(message4)
    serverListener.assertTextMessage(message4)

    // Server to client message that shares context with message1.
    val message5 = message1 + message1
    server.send(message5)
    clientListener.assertTextMessage(message5)

    // Client to server message that shares context with message2.
    val message6 = message2 + message2
    client.send(message6)

    this.executorServiceOrNull = executorService
  }

  internal fun enqueue(call: AsyncCall) {
    this.withLock {
      readyAsyncCalls.add(call)

      // Mutate the AsyncCall so that it shares the AtomicInteger of an existing running call to
      // the same host.
      if (!call.call.forWebSocket) {
        val existingCall = findExistingCallWithHost(call.host)

    concurrently close an SSL socket. This would have appeared in crash logs as
    `NullPointerException: bio == null`.
 *  Fix: Use plus `+` instead of `%20` to encode space characters in `FormBody`. This was a
    longstanding bug in OkHttp. The fix makes OkHttp consistent with major web browsers.
 *  Fix: Don't crash if Conscrypt returns a null version.

 * ## Customize Your Client With newBuilder()
 *
 * You can customize a shared OkHttpClient instance with [newBuilder]. This builds a client that
 * shares the same connection pool, thread pools, and configuration. Use the builder methods to
 * add configuration to the derived client for a specific purpose.
 *
 * This example shows the single instance with default configurations.
