Okhttp: async request doesn't stop immediately after onResponse

First, sorry about my english which is not my native language.

I am using okhttp to make simple asynchronous calls, but my program doesn't stop immediately after the onResponse is called. It takes a few seconds and then stops. I don't have this problem on Android 5, but on my desktop. I have the same problem with other urls. Maybe I did something wrong. The request is being executed on a different thread. My network is under a proxy.

I am using: okhttp-2.4.0

and okio-1.4.0

and java8

.

Please refer me if this issue has already been answered.

This code of mine: `

private final OkHttpClient client = new OkHttpClient();

public void run() throws Exception {

    Settings.setProxy();
    Request request = new Request.Builder()
            .url("http://openlibrary.org/search.json?q=la+famille")
            .build();

    client.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Request request, IOException e) {
            e.printStackTrace();
            System.out.println("error");
        }

        @Override
        public void onResponse(Response response) throws IOException {
            if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

            System.out.println(response.body().string());
            System.out.println("coucou");
        }
    });
}
