Exceptions tacitly swallowed in the game structure

Question

I am having a problem with registration exceptions using the playback platform.

Suppose we have some runnable class RunnableClass that can be initialized in a global class and can be executed in the Executor service.

public class Global extends GlobalSettings {
    @Override
    public void beforeStart(Application app) {
        Runnable runnableClass = new RunnableClass();
        runnableClass.setSmth(new Smth());
        ScheduledExecutorService scheduledExecutorService = Executors.newScheduledThreadPool(10);
        scheduledExecutorService.scheduleAtFixedRate(runnableClass, 0, 1, TimeUnit.MINUTES);
    }
}

Suppose we need to work with the Smth class in the run () method of RunnableClass.

private class RunnableClass implements Runnable {

    private Smth smth;

    public void setSmth(Smth smth) {
        this.smth = smth;
    }

    @Override
    public void run() {
        smth.doSomething();
    }
}

But for some reason we will not get a NullPointerExcception here or any other exception. Obviously, the stack trace of this exception will be logged at least for the console, but I can’t see anything in the console or in the application.log file.

My version of the game is 2.2.1, the sbt launcher version is 0.13.0, the application.conf file is the default.
