rather than all exceptions. Here, we may want to review these exceptions. At least, exception
EOFException shouldn't retry forever.

    exceptionToPolicyMap.put(ConnectException.class, retryPolicy);

    exceptionToPolicyMap.put(UnknownHostException.class, retryPolicy);
    exceptionToPolicyMap.put(ConnectTimeoutException.class, retryPolicy);
