Using couchbase java client within Netty 4.X server


We are using Netty server 4.0.5 and would like to use couchbase java client to connect to couchbase server. My problem is that the couchbase java client (1.3.2) is using netty 3.5.5. So in the same java project we will need to use netty 4.0.5 for the server and netty 3.5.5 for connecting to couchbase - which is not possible as it causes jar conflicts.

Any idea how to solve this?
