kiteConnect.generateSession(requestToken, api_secret) spawns threads that take 5 minutes to expire.


When I use the line kiteConnect.generateSession(requestToken, api_secret) in my code, it spaws OKHttp taskrunner and UrlChecker threads that die out after exactly 5 minutes after the execution of the above mentioned line of code. When the program runs long (places orders and receives web ticker), these threads dont die at all which raises the issue of the clean exit of my program. Can you please guide a little on how these threads are supposed to work, how is their ttyl decided and how can I manage them to do a clean exit of my code?

    Which version of javakiteconnect are you using?
    This unclean exit shouldn't be there on our latest version.

    Am using version 3.1.3 of java kite connect. The threads that don't exit are :

    OkHttp TaskRunner
    OkHttp TaskRunner
    Okio Watchdog
    OkHttp TaskRunner

    Code :
    	public static void testbar()
    KiteConnect kiteSdk = new KiteConnect(api_key);

    String url = kiteSdk.getLoginURL();

    User userModel;
    try {
    userModel = kiteSdk.generateSession(requestToken, api_secret);

    } catch (JSONException | IOException | KiteException e) {
    // TODO Auto-generated catch block

    Thread.getAllStackTraces().keySet().forEach((t) -> System.out.println(t.getName()));

    // Set session expiry callback.
    kiteSdk.setSessionExpiryHook((SessionExpiryHook) new SessionExpiryHook() {
    public void sessionExpired() {
    System.out.println("session expired");

    Can you let us know more about your os, Java and JDK details?

    Here is the output of uname -a :
    Linux PC 5.9.2-arch1-1 #1 SMP PREEMPT Thu, 29 Oct 2020 17:01:28 +0000 x86_64 GNU/Linux
    Here is the output of java --version :
    openjdk 14.0.2 2020-07-14
    OpenJDK Runtime Environment (build 14.0.2+12)
    OpenJDK 64-Bit Server VM (build 14.0.2+12, mixed mode)

    I created a new project with the following maven dependency to make sure I wasnt using the old libraries :

    <code class="CodeInline">
    <!-- -->

    Does the testbar() which I wrote above reproduce the issue at your end?
  • sujith
    But then how did you conclude that it takes 5 minutes to expire?
    Signal Dispatcher
    OkHttp TaskRunner
    Reference Handler
    Okio Watchdog
    Monitor Ctrl-Break

    Process finished with exit code 0
    This is the output for me.

    If you look at the runtime in the attached image in my previous reply, its from 10:35:49 to 10:40:50. If I use proper logging, this time is always exactly 5 minutes.

    KiteRequestHandler class has the OkHttpClient which is used to make requests and that is created only once and reused.
    Can you try to fork javakiteconnect and try calling client.getDispatcher().getExecutorService().shutdown(); once you are done?

    Let us know if it works.
