Moreover I want to mention there is a conflict for people relying on Netty 4.1.77:

io.lettuce.core.RedisConnectionException: Unable to connect to localhost:49462
Caused by: io.netty.handler.codec.EncoderException: java.lang.NoSuchMethodError: io.netty.util.internal.ReferenceCountUpdater.setInitialValue(Lio/netty/util/ReferenceCounted;)V
