java.lang.ClassCastException JedisPool Multithreading

[Wahyd Mnémoi]

Hi,

First, sorry for my poor english, i'm not very fluent. I'm getting an class clast exception. I thought it could be due to the implementation of my JedisPool or the way i release jedis instance, so here the code

for the instanciation of my JedisPool : 

    static {

        JedisPoolConfig config = new JedisPoolConfig();

        config.setTestOnBorrow(true);

        pool = new JedisPool(config, "localhost");

    }

for the method where it throws the exception 

    public static Set<String> testgetEntries() {

        Jedis j = null;

        try {

            j = pool.getResource();

        } catch (Exception e) {

            LOGGER.error(e.getMessage(), e);

        }

        try {

            String key =" something"

            double minmaxScore = 23

            Set<String> result = j.zrangeByScore(key, minmaxScore, minmaxScore);

            return result;

        } catch (JedisConnectionException e) {

            LOGGER.error(e.getMessage(), e);

            if (j != null) {

                pool.returnBrokenResource(j);

                j = null;

            }

        } finally {

            if(j != null)

                pool.returnResource(j);

        }

        return new HashSet<String>();

    }

Any ideas on where it is going wrong?
