Sometimes get different value for the same key

[Epica-Wang]

Just found that this redis client can not assure to always return same value for the same key.
Please see the example below where I tried to access key myRedis:value several time, but there is only 2 times it returns the correct value Success(-0.91666666666666663).
Guarantee that no modification to value of this key during test blow

scala> redis.send("""GET "myRedis:value"""").map(s => s)
res10: scala.concurrent.Future[String] = Future(Success())

scala> redis.send("""GET "myRedis:value"""").map(s => s)
res11: scala.concurrent.Future[String] = Future(Success(-0.91666666666666663))

scala> redis.send("""GET "myRedis:value"""").map(s => s)
res12: scala.concurrent.Future[String] = Future(Success(-0.91666666666666663))

scala> redis.send("""GET "myRedis:value"""").map(s => s)
res13: scala.concurrent.Future[String] = Future(<not completed>)

scala> redis.send("""GET "myRedis:value"""").map(s => s)
res14: scala.concurrent.Future[String] = Future(Success())

I know it is too late to respond to this issue. I am not actively maintaining this project anymore. But to explain the behavior - it is due to the characteristics of future - if it completes and brings a non null value - it is guaranteed to be correct. Hope this helps.
