Blocking operation doesn't return even though the client has been closed

[EricChan999]

My test is:
Create a child thread and it do BRPOPLPUSH for blocking itself to wait for data from redis, and then close the redis client(close the socket InputStream and OutputStream) in main thread, suppose the child thread should return by IOException throwing, but it is still blocked and it never returns until any reponse is received from redis.

I wasn't able to reproduce with the above test. Are you doing something different?

Below is my code, the "End" string is never printed due to the blocking of brpoplpush. Is there any wrong with my code?
My redis is 2.6.12, and the redis-protocol is 0.7.

public static void main(String[] args) throws IOException {
    final RedisClient redis = new RedisClient("192.168.1.103", 6380);
    new Thread() {
        @Override
        public void run() {
            try {
                Thread.sleep(3000);
                redis.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }.start();

    redis.brpoplpush("test1", "test2", 0);
    System.out.println("End");
}
