Upgrade netty to the latest 4.2.x version.
It might require to follow the migrating guide and adapt some changes.
It could be locked behind a system property.
Also, following recent issues observed with the new netty allocator present in netty 4.2 it should set it manually and make it also behind a system property.
Describe alternatives you've considered.
Keep netty 4.1.x and add the incubator module which has been archived.
