setting keys does not seem to work with redis-server 2.2.9

[pk11]

scala> val r= new com.redis.Redis("localhost",6379)
r: com.redis.Redis = localhost:6379 connected:true

scala> r.set("testkey","sdfsdfdsf")
res1: Boolean = true

scala> r.get("testkey")
res2: Option[String] = Some(9)

Same with 2.6.16
