redis - Redisson.create が IllegalArgumentException で失敗する: ホスト名を null にすることはできません

Question

Redisson を使用して (Docker 上で) Redis に接続しようとしています...簡単なもの..

Config config = new Config(); config.useSingleServer().setAddress("redis://192.168.99.100:6379"); RedissonClient redisson = Redisson.create(config);//3行目

しかし、このエラーが発生しています (3 行目) - 何か不足していますか?
