Shutdown

How to close client correctly ? When I just finish application, JVM catches SIGSEGV:

A fatal error has been detected by the Java Runtime Environment:

You must send TdApi.Close() and wait for the TdApi.Ok response.
If you want to make sure that tdlib is closed when the app is closed, you must send TdApi.Close() and wait for its response in a shutdown hook.

Runtime.getRuntime().addShutdownHook(new Thread() { 
  public void run() { 
    // Send here TdApi.Close(), and wait for TdApi.Ok response
  } 
});
