Jedis pool stops working when another instance uses PubSubs

I'm currently creating 2 java programs which should (but must not) work side by side.For simplicity call them S1 and S2.

S1 is a simple API that pulls or pushes data from/to redis. For this I initialize a JedisPool on startup and later use this pool to interact with redis.

S2 is a system that communicates in realtime with a master using PubSub.

Creating the pool:

private JedisPool jedisPool;public void startup(){        JedisPoolConfig poolConfig = new JedisPoolConfig();        poolConfig.setMaxTotal(128);        jedisPool = new JedisPool(poolConfig, "127.0.0.1", 6379, 10000);}

And using it later

    public void set(String key, String value) {    Jedis jedis = null;    try {        jedis = Main.getInstance().getJedisPool().getResource();        jedis.clientSetname(key);        jedis.set(key, value);    } catch (Exception ignored) {        ignored.printStackTrace();    } finally {        jedis.close();    }}

This works perfectly fine.

Creating the pubSub for system 2:

public static void runPubSub() {    new Thread(() -> {        Jedis jedis = null;        try {            jedis = new Jedis();            JedisPubSub jedisPubSub = new JedisPubSub() {                @Override                public void onMessage(String channel, String message) {                    if (channel.equals(Main.getInstance().getTypeManager().getName())) {                        //handle Command                    }                }                @Override                public void onSubscribe(String channel, int subscribedChannels) {                    System.out.println("Client is Subscribed to channel : " + channel);                    System.out.println("Client is Subscribed to " + subscribedChannels +" channels");                }                @Override                public void onUnsubscribe(String channel, int subscribedChannels) {                    System.out.println("Client is Unsubscribed from channel : " + channel);                    System.out.println("Client is Subscribed to " + subscribedChannels +" channels");                }            };            jedis.subscribe(jedisPubSub, Main.getInstance().getTypeManager().getName());        } catch (Exception ex) {            System.out.println("Exception : " + ex.getMessage());        } finally {            if (jedis != null)                jedis.close();        }    }).start();}

Now to the specific problem:As soon as I start both, S1 and S2, then S1 stops working. S2 works fine.When using only S1 everything works fine.

Can anyone help me out here?
