ClassCastException java.lang.Long cannot be cast to [B

I often get this error both from WorkerImpl and ClientImpl.（Regarding this post: redis/jedis#186 ）

Is it feasible for both WorkerImpl and ClientImpl use pool connection rather than single Jedis instance? Or is there a way to avoid frequently recreating WorkerImpl and ClientImpl?

@RonankiM According to redis/jedis#186, the issue was due to using Pool.returnResource() instead of Jedis.close(). Can you confirm this fixes your issue?
