Can't interrupt a thread doing BRPOPLPUSH.

I would like to be able to interrupt() a thread doing BRPOPLPUSH. Specifically, if nothing has been popped yet, I want jedis.brpoplpush() to be able to throw an InterruptedException, so the thread can die.

This has been a source of hangs in my program, so for the moment I’m working around this with a manual while { jedis.rpoplpush(); sleep(); } that is interruptible.

Specifically, if nothing has yet been popped (e.g., a work queue is empty), it would be good if the command could be interrupted.

Is it expected behavior to get no exception at all when I am stopping a web app with tomcat stop.

public class MyContextListener implements ServletContextListener {
    private final DataListener RawListener = new DataListener();

    @Override
    public void contextInitialized(ServletContextEvent sce) {
        RawListener.start();
    }

    @Override
    public void contextDestroyed(ServletContextEvent sce) {
        RawListener.interrupt();
    }
}

On a jax-rs web app having this context with below Thread is not triggering any exception at all.

public class DataListener extends Thread {

    private boolean dataProcessOn;

    public DataListener() {
        super("DataListener");
        dataProcessOn = true;
    }

    @Override
    public void run() {
        while (dataProcessOn && !this.interrupted()) {
            try (Jedis redis = RedisPool.getJedis()) {
                final String baseData = redis.brpoplpush(
                        "rawdata:stream",
                        "ws:v1:rawdata:processing",
                        0);

                processData(baseData);
            }
        }
    }
}
