title: Redisson library used with Redis throws RedisConnectionException
body: <p>Redisson (<a href="https://github.com/redisson/redisson" rel="nofollow noreferrer">https://github.com/redisson/redisson</a>) throws org.redisson.client.RedisConnectionException when i'm trying to update some redisson variable and the underlying redis is down. So, why does it not mention in the code: something like 
  throws org.redisson.client.RedisConnectionException for all the methods ?</p>
  
  <p>I wanted to use this library because it lets me set timeouts for individual entries of a hashmap. I'm going to use it in my production applications. Is it safe to use it ?</p>
